摘要

为了克服大气无线光信道中光强闪烁带来的长突发错误

本文提出了一种基于光子计数的迭代译码方案

并分析基于大气无线光信道下的译码性能.仿真结果表明

本方案不仅提高了系统的抗突发错误性能

并且与传统的信道交织+级连码方案相比

具有不引入信道交织时延和易于硬件实现的优点.

Abstract

In order to overcome long burst error induced by scintillation in atmospheric optical wireless channel

the paper proposes an iterative decoding scheme based on photons counting and analyzes performances of the iterative decoding scheme over atmospheric optical wireess channel.Compared with former channel interleaving+Concatenated codes scheme

the scheme significantly improves anti-jamming performance of system without channel interleaving delay

and the scheme reduces complementation complexity.
