Full textRealiza un análisis de las características técnicas de TD-SCDMA (Acceso síncrono múltiple por división de código y división de tiempo), el cual ha sido aprobado por la UIT como estándar oficial 3G. TD-SCDMA es un estándar 3G desarrollado por la Academia China de Tecnología de Telecomunicaciones y utiliza acceso múltiple por división de código (CDMA) y multiplexación por división de tiempo (TDD) para soportar en un mismo canal físico transmisiones de downlink y uplink. Este aspecto, junto con otras características técnicas de TD-SCDMA, son estudiados y evaluados para determinar las ventajas técnicas que ofrece con respecto a WCDMA. Así mismo, se realiza una comparación integral entre WCDMA y TD-SCDMA enfocando los aspectos de capacidad y cobertura. En esta comparación se incluirá el uso de HSDPA para ambas tecnologías. Por último se exponen aspectos comerciales sobre ambas tecnologías y se concluye con una recomendación sobre la viabilidad de implementar TD-SCDMA para un operador celular. Se deja en claro que tarde o temprano el mercado de servicios 3G va a despegar de manera agresiva y para entonces los operadores de red y proveedores de contenidos deberán estar preparados para prestar servicios avanzados relacionados con internet y aplicaciones basados en IP de alta velocidad, comercio electrónico, servicios basados en la ubicación del usuario, etc. En la actualidad, los 3 operadores de telefonía móvil nacionales ya tienen implementadas y en fase de desarrollo sus redes 3G y por esta razón no se aborda un estudio de factibilidad de implementar 3G, simplemente ya es una realidad.

Full textWith a growing number of consumers utilizing the Internet, companies have foreseen a consumer demand for high-speed wireless access. Since current mobile cellular systems can transfer at most 115.2 kbps per user, a third generation of mobile cellular service has been under development by various organizations since 1997. This new generation of technology will support data rates up to 2 Mbps for stationary mobiles and up to 144 kbps for vehicular traffic. This thesis focuses mainly on TD-SCDMA, one of many candidates submitted to the International Telecommunications Union for third generation review. The standard, developed in China by the Chinese Academy of Telecommunications Technology, employs both code-division multiple access and time-division duplexing to support both forward and reverse transmissions on one physical layer. This aspect, along with other common features of TD-SCDMA, will be studied and evaluated to determine if this new technology is a viable option for future commercial or military deployment.

This thesis is focused on the development of TD-SCDMA standards of G3 (the third generation) in Mainland China, especially some key techniques. The outline of this thesis is as below: Chapter 2 introduces TD-SCDMA systems, and brings out the discussion on the function of its physical layer; the calculation of Smart Antenna is demonstrated and analyzed in Chapter 3. As there are not enough conditions given in the real operation plus a real-time need to include in the calculation; hence, we use LMS and RLS calculations to simulate the effect of Smart Antenna Array. However, the angle differentiation functions of LMS and RLS calculations are not quire poor, and therefore, we are forced to compare the angle differentiation functions of CAPON and MUSIC calculations, and decide to take MUSIC as the differentiation method. In Chapter 4 the calculations of Chapter 3 are brought in the structure of TD-SCDMA systems to simulate its performance efficiency in this calculation. First, we simulate the efficiency of the user’s angle positioning differentiation tracker to evaluate the success rate of the non-interfered and variously interfered escalating key angle differentiation efficiency, and the differentiation efficiency rate of a changing power station in the non-power control, and infer from these findings the differentiation efficiency rate of the escalating keys under some given circumstances. Chapter 5 offers the conclusion from the previous discussions and some suggestions for future researches.

The exponential step size LMS algorithm for smart antenna application has been proven with fast convergence speed than conventional LMS Algorithm. However the convergence speed is still slower than RLS algorithm. In this thesis, we propose a novel method that is using the ES-LMS algorithm with constant modulus algorithm (CMA) which can offer simple computation and fast convergence speed than normal LMS, ES-LMS, and even RLS. The LMS and CMA algorithm are both blind equalization. The multiple signal classification (MUSIC) algorithm is also employed for the DOA estimation and a classical beamforming technique to select the weights of the array elements has been used. Computer simulation is conducted under the environment of TD-SCDMA systems.

Compared to 2nd generation Mobile system (GSM, etc), the 3rd generation Mobile system can have much higher transmission data rate and larger user capacity is due to the adoption of CDMA (Code Division Mulipla Access) technology. But CDMA requires more precise synchronization. Within the three major 3G Mobile systems, the China developed TD-SCDMA system requires more precise synchronization than others since the system requires all of the user signals reach the Base Station at the same time. This requirement fully effective the orthogonality of CDMA system and brings superior performance. But the synchronization procedure, especially the down link synchronization, requires the user’s handheld Mobile Station to have a huge amout of correlation calculation as up to 2500 MCMPS (Millions of Complex Multiplications Per Second) based on complicated circuit design. Even with FFT/DFT circuit, it still needs 250 MCMPS. This consumes lots of electric power and also rises up the hardware cost of the Mobile Station. Though a paper from IEEE [8] has proposed an approximation method to reduce the calculation times down to 28 MCMPS, but it need the DFT/IDFT circuit and need to calculate 30-subframes for sufficient accurate result. This thesis propose an improved method based on the subframe structure of TD-SCDMA system and utilizes the statistics with detection window to identify the timing point of the Guardband duration, which resides between DwPTS and UpPTS. Then the correlation calculation starts on the DwPTS (SYNC_DL code) of the next subframe. The correlation calculation will be reduced to only 2 MCMPS with only 6 subframe times while without the need of DFT/IDFT circuit.

The specialty of the technology industry development in China is that the industry technical capacity still in the developing countries list, but there are huge elements of the consumer market and the scale advantages. China has better development conditions than other developing countries. It can seek different development strategies and experiences with other less developed countries to attempt the technology and market challenges of global production networks and the existing power and value structure. However, given market scale advantages of China's development does not guarantee success. To China's technology industry, the rapid development of the technology industry to highlight the low level of civil technical defects and become a major development restrictions. To the China government, how to build national forces to reach their own intellectual property rights and industrial upgrading, is worthy of discussion. China case is different with other less developed country. How does China use advantage conditions for the development to challenge to a power contest with flagship transnational corporations? We think of China have the huge elements of the consumer market and the institution power backing of the special political system. And we think of that these conditions make up China economic and technical reach. In the part of theory discussion, the context is about power system in global production network. How does the GPN’s governance make changes after China into competition? In the part of case study, the context is about the development process of TD-SCDMA. Finally, the context analyses actors’ strategy and action for development process of TD-SCDMA. This paper holds that the development of TD-SCDMA is China government-led, and joint foreign-funded and domestic enterprises. Now standardization and industrial development of TD-SCDMA have began to take shape. China’s independent technical standards strategy is successful. In particular, The China government can maintain global production network in the initiative. And this is a very rare case in less development countries. However, We cannot assure of TD-SCDMA can get enough market share after opening 3G market. Because China enterprises operate in the market-capacity still much lags behind the flagship transnational corporation. And these disadvantaged is not part of the China government to resolve. So the next stage of commercial will be the impact of TD-SCDMA success or not.

Since China implements the economic reform and opens, in the face of the that economy grow up constantly under China threaten, it regard as it by rival not surging of industry development of future successively already countries all over the world,This kind of situation is the most obvious in Hi-Tech industry, moreover, because Chinese Government realizes that will create the powerful countries of economy and science and technology further, must grasp high industry surtax value , devoted to developing the independence more standard in recent years, expect to integrate with the industry development, and complement each other then bring about an advance in a local products industry. But in numerous independence standards, in the course of promoting with standard TD-SCDMA of 3G, relatively attracted attention by world, submitted ITU and began to pass for more than 7 years so far by oneself, but brought up much communication industries of native country and became international and famous enterprises during that time , development relation and its way among them, are really worth studying further. Here originally in the article, environment and background developed with the whole China development TD-SCDMA industry standard , the whole world and native country communication industry, to describe and analyse the whole industry''s standard and relation of a local products industry development, and follow the standard competition theory and diamond model to confirm mutually on the materials of the income , hope to make use of this searching to happen under the prerequisite taking China TD-SCDMA standard as research object, industry''s standard and a relation developing of local products industry . Except in distinguish purpose industry standard and copies of local products industry develop relation among of research this, can offer the another kind angle and view to the standard and industry development further too, and expect to cause more different research that face and discuss with this text, in order to reach the final goal casting a brick to attract jade.
