深空通信信道编码方式研究
首发时间:2014-07-25
摘要:现代深空通信的快速发展对深空通信可靠传输技术的要求越来越迫切,选择一种有强纠错能力的信道编码成为必须。本文用AWGN 信道对深空通信信道进行模拟,将近年来信道编码领域的两个研究热点--TPC码和LDPC码的性能以及实现复杂度进行了对比,在综合考虑了性能、编译码复杂度以及硬件平台实现可行性的情况下,最终选择了TPC码应用于实际的深空通信系统当中。并对 TPC 码的相关性能以及算法的理论和工程优化做了进一步的研究。?????

Research on Channel Encoding and Decoding Technologies
Abstract:Modern deep space communication's rapid development brings pressing needs of the reliable transmission technology, this leads to choose one channel encoding and decoding solution with strong error-correcting ability.This paper simulate two research hotspots of current channel encoding and decoding field, TPC code and LDPC code,under the AWGN channel, and compare the implement complexity.After take into acount the performance, complexity and the feasibility on hardware,we choose TPC code to use in our real system, and do more research on improving TPC code's performance and optimizing the algorithm in theory and engineering.?????
Keywords: Deep space communication channel encoding and decoding TPC LDPC?????
