| 摘 要： | 传统基于RS-Turbo码的系统需要提供RS译码及Turho译码2种不同的译码算法需求,使得译码器的软硬件设计复杂化,无法满足无人机通信要求.从理论上分析了Turbo码的性能特点,提出一种改进的二维turbo迭代算法,并应用在无人机通信仿真中.仿真结果表明该算法在低信噪比时能够提升误码率性能,且易于工程实现.

| Abstract: | Traditional system based on RS-Turbo code needs RS decode and Turbo decode,resulting in complex hardware design.It can't satisfy demand of the communication in UAV.This paper introduces the principle of Turbo encoding and proposes the 2-D turbo iteration decoding algorithm in details.Base on the MAP algorithm,the paper brings forward an UAV communication coding scheme.The simulation results show that the scheme can better the BER performance at low SNR,and can be implemented easily. |
