碩士 === 國立交通大學 === 電子工程學系 電子研究所 === 103 === Recently, wireless communication systems become popular. Among the dominant factors of affecting system performance, the channel fading effect and noise, usually modeled as additive white Gaussian noise (AWGN), are most common. Rayleigh fading channel is a popular channel model. In this thesis, we investigate different channel models, and design an error correction code to mitigate the channel effect. We use the combination of low-density parity-check code (LDPC) and turbo product code, and we find that it is an effective way to defend the different channel conditions. This thesis is organized as follows. Chapter 1 introduces the motivation. Chapter 2 introduces the low-density parity-check code (LDPC). Chapter 3 introduces the product code, turbo product code and simulation with the combination of turbo product code and LDPC code. Chapter 4 introduces various channel models. Chapter 5 presents the simulation of our error correction method, and discusses the simulation result. Last, in chapter 6, we summarize this thesis and propose future work directions.
