FQPSK
本论文首先介绍了当前深空通信的编码调制技术的现状与发展，阐述了以往
的深空通信中的编码和调制技术的方案和局限性，提出LDPC码和FQPSK调制的
优越性和发展前景。第二章描绘了LDPC码的奇偶校验矩阵的图形表示、生成方
式和译码方法，并比较二元LDPC码和多元LDPC码的优越性和实现问题。第三
章在介绍FQPSK调制的方案的由来、改进和发展的基础上，对其进行了功率谱分
析，介绍了一些常规的解调方案。(This paper introduces the current situation and development of the technology of deep-space communication code modulation on the coding and modulation techniques in deep space communications program and limitations of the proposed of LDPC codes FQPSK modulation superiority and development prospects. Chapter II depicts a graphical representation of the LDPC code of the parity check matrix generation method and decoding method, and compare the superiority of binary LDPC codes and multiple LDPC code and implementation problems. Chapter origin in the introduction FQPSK modulation program, improvement and development on the basis of its power spectrum analysis, conventional demodulation.)
