应用于深空通信中Turbo码的研究

Turbo Codes in Deep Space Communication

在对Turbo码编解码的基本原理和其在深空通信环境下的应用特点分别进行介绍的基础上,以深空通信中用的Turbo码作为纠错码这一编码的码率,对交织长度及跌代次数进行了仿真.仿真结果与理论值较接近.根据仿真探讨了Turbo码在深空环境下应用的优点,有助于进一步研究Turbo码在深空通信中的应用.

On the basis of the simple introduction for Coding and Decoding of Turbo codes and the deep - space communications, code rate, interlaced length and iterative number of Turbo codes for deep -space communications are simulated by using computer in this paper. The simulation value approaches the theoretical value, and through the simulation the analyses for the results are given, and it is known that Turbo codes fit deep - space communications and is helpful to further researchs.
