无人机数据链中Turbo码应用研究

Turbo码具有接近Shannon限的性能,它的出现是信道编码理论发展史上的一个里程碑,Turbo码的优异性能依赖于较长的交织器和进行多次迭代译码.而在无人机通信系统中,由于实时性的要求,无法使用很长的交织器和多次迭代.因此,必须对Turbo码的应用进行研究,文中通过仿真研究了Turbo码用于无人机数据链的一些关键问题,得出适用于无人机信道下的Turbo码的具体参数,提高了无人机的通信质量和抗干扰性能.

Study on Application of Turbo Code in UAV Data Link System

Turbo Codes is a new kind of error-correcting codes that can approach the Shannon bound, and is considered as one of the most exciting and potentially important developments. The significant performance of Turbo code relies on large interleaver size and many times of iteration. However, in the communication systems of UAV, it can not be employed due to the real time restriction. So the study on application of Turbo codes should be carried out, and some problems are discussed by using simulation tools when u...
