摘要
Turbo码是一种性能优异且高效的信道编码方式,被空间数据系统咨询委员会(CCSDS)推荐为深空通信中可采用的信道编码方案之一。分析了Turbo码的编码和译码的基本原理,基于CCSDS给出的深空通信标准,设计并实现了Turbo码的编码和译码过程。通过Matlab软件仿真测试,初步探究了译码迭代次数、码率、译码算法等因素对误码率性能的影响,并对仿真结果进行了分析。
Turbo code is an excellent and efficient channel coding scheme,recommended by CCSDS（ Consultative Committee for Space Data System） as one of channel coding in deep space communication.Firstly,this paper introduces the basic principle of coding and decoding in Turbo code.Based on CCSDS standard in deep space communication,the implementation and simulation of Turbo coding and decoding is presented.Some parameters which may influence BER performance are simulated by Matlab software,such as iteration times,code rate,and decoding algorithm.Some analysis based on simulation results are given further.
