  2. The forth chapter focus on the researches of decoding algorithm, first studies the decoding theory and decoding approaches of several iterative message passing algorithms for ldpc code, because of the conflict between simplification and reduced performance of bp decoding algorithm, the thesis analyzes the calculation complexity of each algorithm, and simulates the performance of each algorithm, by considering the tradeoff between hardware complexity and error performance, we get two algorithms which are much easier to implement : bp - based and normalized bp - based decoding algorithm, especially, the last one achieves considerable improvement with almost the same complexity

    第四章對ldpc碼譯碼演算法進行了深入研究,給出了基於置信傳播的幾種譯碼演算法的原理和步驟,圍繞著bp演算法的簡化與譯碼性能下降的矛盾,研究了每一種譯碼演算法的復雜度分析,並相應地給出了每一種譯碼演算法的模擬性能曲線,綜合考慮譯碼性能和譯碼復雜度兩個方面,從而得出了適合硬體實現的演算法: bp - based和normalizedbp - based演算法,後者在基本不增加譯碼復雜度的情況下,對譯碼性能有較大的提高。
