Streszczenie:

[Truncated abstract] The transmission of digital information over a wireless communication channel gives rise to a number of issues which can detract from the system performance. Propagation effects such as multipath fading and intersymbol interference (ISI) can result in significant performance degradation. Recent developments in the field of iterative detection have led to a number of powerful strategies that can be effective in mitigating the detrimental effects of wireless channels. In this thesis, iterative detection is considered for use in two distinct areas of wireless communications.

Shingled Magnetic Recording (SMR) technology is important in the immediate need for expansion of magnetic hard disk beyond the limit of current disk technology. SMR provides a solution with the least change from current technology among contending technologies. Robust easy to implement Digital Signal Processing (DSP) techniques are needed to achieve the potentials of SMR. Current DSP techniques proposed border on the usage of Two Dimensional Magnetic Recording (TDMR) techniques in equalisation and detection, coupled with iterative error correction codes such as Low Density Parity Check (LDPC).

Streszczenie:

While network data transmission was traditionally accomplished via routing, network coding (NC) broke this rule by allowing network nodes to perform linear combinations of the upcoming data packets. Network operations are performed in a specific Galois field of fixed size q. Decoding only involves a Gaussian elimination with the received network-coded packets. However, in practical wireless environments, NC might be susceptible to transmission errors caused by noise, fading, or interference. This drawback is quite problematic for real-time applications, such as multimediacontent delivery, wher

Shannon’s source and channel-coding separation theorem has been the basic philosophy followed by most state-of-the-art wireless transceivers, where all source signals are assumed to have the same importance and are protected equally by the channel encoder. However, due to its assumption of using idealized Gaussian channels, potentially infinite encoding/decoding delay as well as complexity, Shannon’s source and channel-coding theorem is not strictly applicable in practical wireless scenarios. This is because it is almost impossible to remove all the redundancy of the video source, therefore th

碩士<br>國立中山大學<br>通訊工程研究所<br>107<br>The fifth generation mobile network (5G), also known as New Radio (NR), is expected to be commercialized in 2020. The 5G NR operates including the sub-6GHz frequency bands and millimeter wave bands. In the non-standalone mode, the millimeter wave bands are operated with the aided by sub-6GHz bands. In the standalone mode, the sub-6GHz and the millimeter wave bands can be operated independently. Time Division Duplexing (TDD) mode is usually adopted in the standalone mode. Effectively operating the communications between base station and the user equipment in th

碩士<br>國立交通大學<br>電信工程系所<br>97<br>An iterative receiver structure for joint channel estimation, symbol detection and channel decoding is proposed for the non-coherent decoding of the low-density parity check code in Rayleigh fading channels. Performance of the proposed algorithm is studied for both the flat and frequency-selective fading channels without using any pilot or training symbol. In flat fading channels, simulation results show that the performance of the non-coherent algorithm is only half decibel inferior to the coherent one, which matches the analysis using extrinsic information tra

碩士<br>國立暨南國際大學<br>資訊工程學系<br>101<br>Arithmetic coding (AC) is an efficient data compression technique and widely adopted in image and video compression standards. However, the high complexity of arithmetic coding in computation is the bottleneck that many researchers endeavor to overcome. Piecewise integer mapping based arithmetic coding can eliminate all multiplicative operations in both encoder and decoder by the technique of replacing them with the operations of comparison and addition. It can reduce the computational complexity with a little penalty of compression loss. A generalized piecew

碩士<br>國立臺灣科技大學<br>電子工程系<br>103<br>Multi Input Multi Output (MIMO) technology plays an essential role in modern wireless communication system owing to its capability to significantly improve communication quality and efficiency without drastically increasing the occupied bandwidth. However, such lucrative features also come along with the prominent drawback of significantly increased system complexity, especially on the receiver side. It has been shown that the Joint MIMO Detection and Channel Decoding (JDD) scheme can effectively reduce the complexity and improve the signal quality of the MIMO
