简介深空通信的发展现状和 Turbo码的基本原理。着重研究深空通信中 Turbo码技术的算法和应用 ;并通过仿真对 Turbo码和其它传统码的性能进行比较分析。针对深空通信的特点 ,就
It is well konown that Turbo codes can approach Shannon Limit,so it is widely used in various fields including Deep Space Communication(DSC).Turbo codes provide up to 0.8dB improvement in E b/ N o over the current best codes used by deep space mission.In this paper,an overview of the trend in DSC and the rationale of Turbo codes are introduced briefly.The algorithms and applications of Turbo codes used in DSC are analyzed with a great emphasis and the performance analysis of Turbo codes comparing with other traditional codes is simulated.Finally,aiming at the characteristic of DSC,several technological issues on the implementation of Turbo codes are discussd.
