Abstract:

The objective of the thesis is concerned on the problem of detecting superpositional signals in a wireless channel. In many wireless systems, an observed signal is commonly represented as a linear combination of the transmitted signal with the interfering signals dispersed in space and time. These systems are generally known as the interference-limited systems. The mathematical model of these systems is generally referred as a superpositional model. A distinguished characteristic of signal transmission in a time-varying wireless channel is that the channel process is not known a priori. Reliab

Abstract:

This dissertation describes a novel method of providing position-location from geosynchronous communication satellites. The Global Positioning System (GPS) has become the standard for position-location and navigation in the world. It provides extremely accurate coordinates to military users and slightly less accurate coordinates to "non-authorized" users. Disadvantages of GPS are complexity and high cost. The U.S. Department of Defense (DoD) has spent billions of dollars in developing and fielding the system. Maintenance and GPS satellite replenishment costs will continue to climb. A simpler,

The localization of wireless devices, e.g. mobile phones, laptops, and handheld GPS receivers, has gained much interest due to the benefits it provides, including quicker emergency personnel dispatch, location-aided routing, as well as commercial revenue opportunities through location based services. GPS is the dominant position location system in operation, with 31 operational satellites producing eight line of sight satellites available to users at all times making it very favorable for system implementation in all wireless networks.

This study not only conducts literature review but also conducts surveys with senior experts to find out what’s the trend of GPS. This study sums up GPS related literature and senior experts in GPS industry as conclusions. The result shows that the integration of different system must be the trend, the network RTK (Real - time kinematic) and PPP (precise point positioning) technology could greatly improve the position

Using GPS positioning and digital maps, it always takes lots of time to locate the position. If the traffic information could be transmitted to other vehicles while driving, the application of GPS could be enlarged. In this thesis, we use add direction and speed parameter of coordinates for AIS concept which is applied to improve the accuracy of the Global Positioning System (GPS).

Traditionally using the test equipment with antenna and “DUT(Device Under Test)” to find out the value of the signal strength is the most popular method to find out the DUT performance in the specific test environment. By using this method we can find out the relationship between the channel model and our test environment after analysis the test results. Raylei

碩士<br>國立臺北科技大學<br>機電整合研究所<br>96<br>Global Position System (GPS) is broadly used in military or civil navigation devices. GPS can work for a long time and its output can still remain stable. But it is easily interfered by external factors such as weather, building and etc. Inertial Navigation System (INS) doesn’t have the above defects of GPS but its accuracy is reduced by integration errors. Integration errors come from many factors. The errors are mostly caused by output errors and axis misalignment factor. Therefore, calibration and compensation of output errors are required before apply I

碩士<br>國立交通大學<br>電信工程系所<br>92<br>In this thesis, we demonstrate a low power synthesizer for global position system (GPS) which operates at 1.57GHz. For low power consumption consideration, we set the supply voltage at 1.5V, and adopt the “Integer-N” type frequency synthesizer to save power. For high integration issue, all circuits are integrated in single chip except the loop filter and the reference oscillator. This chip is fabricated by TSMC 0.25um. The measurement of power consumption is 14.1mW for 1.5V supply voltage. VCO consumes 6.8mW, frequency divider consumes 6.6mW, charge pump cons

When the vehicle enters the tunnel and losing the GPS signal, the RFID readers inside the tunnel can scan the tag and provide the position information of vehicle. The area location sensing method is used in our approach. The tunnel can be divided into many area segments and the center of each segment has a preset GPS coordinate.
