摘要: 
近年來由於行動通訊技術發達,使用者對於傳輸品質的要求也越來越高。
而行動機台的要求也趨向迷你化跟個人化,在這種背景之下手機的功率控制也越來越重要,為了能在低功率之下達成一定的錯誤控制效果,使用錯誤更正編碼是一種不可避免的技術。
本文主要介紹錯誤更正編碼中的低密度查核碼,除了介紹如何建構一個簡單的低密度查核碼、低密度查核碼的軟式解碼之外,本論文也介紹在衰減通道之下低密度查核碼的效能。目前許多關於低密度查核碼在衰減通道的效能模擬均只侷限在雷萊衰減這種狀況的通道之中,然而行動通訊中除了雷萊衰減之外,還有更多的狀況,例如多了遮蔽效應的鈴木通道跟多了主要信號的萊氏通道。這類模擬至今尚未有人提及。本論文中將會去模擬在這些通道中低密度查核碼的改善效能的情況。

Mobile communication technology is development in recent years.
Users request the data-transmission quality higher and higher and
the mobile phone are mini and personal. In the condition, the power-
control is important.
Because we want to achieve good performance of data-transmission on lower power, the Error-Control-Coding is an inevitable techno-
-logy. The thesis introduces the “Low Density Parity Check Code”
, which is look at attentively in recent years. In addition to introduce that how to construct a simple LDPC code and soft-decision
decoding of LDPC codes, the thesis will introduces the performance
of LDPC codes on fading channels. Many papers propose the performance
simulations of LDPC codes on Rayleigh fading channel. But there are
furthermore effect on fading channel, for example Rice fading, which
contain LOS component and Suzuki fading, which contain shadowing component. The thesis will propose the simulations on Rice channel
and Suzuki channels.
