【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.更多还原
