摘要 阐述了低密度奇偶校验码的发展、定义、编译码方法。通过对LDPC码和Turbo码的比较和分析,得出LDPC码的整体性能要优于Turbo码。文中还讨论了LDPC码的应用,主要是在STC-OFDM系统中的应用。最后,对低密度奇偶校验码的未来的研究方向进行了展望。 This paper introduces the development, definition, encoding and decoding methods of LDPC codes. A comparison of LDPC codes with Turbo codes shows that LDPC codes have better performance than Turbo codes. This paper also introduces the application of LDPC codes, especially its application in the STC - OFDM system. Finally, it discusses the future researches on LDPC codes.
