摘要
Turbo码的优异性能依赖于两个条件来获得:使用长的交织器和进行多次迭代译码。而在某些通信系统中,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码做某些改动。该文简单介绍了无人机的测控通信平台,提出了Turbo码在无人机测控信道中使用时需要解决的问题。通过仿真研究了Turbo码用于无人机测控领域的一些关键问题。
Turbo Code's significant performance dependents on two facts:large interleaver size and many times of iterative decoding.But in some communication systems ,large size interleaver and many times of iterative decoding can't be employed because of real time restriction.In such systems ,changes must be made for original Turbo code.In this paper,the UAV remote control system is introduced.Then problems that must be considered when using Turbo code in UAV remote control channel are discussed.The writer has also studied these problems by using simulation tools.
