摘要 在不考虑噪声和仅考虑散粒噪声两种情况下 ,分析了 Turbo码对二进制脉冲位置调制( BPPM)的快跳频光码分多址 ( FFH OCDMA)系统性能的影响 ,并对该系统进行了数值模拟 .结果表明 ,Turbo码对 BPPM调制的 FFH The performance of Turbo-coded optical fast frequency-hopping CDMA network (FFH OCDMA) using binary PPM modulation (BPPM) was analyzed. The analysis results show that, whether considering no noise or considering shot noise, Turbo-coded FFH OCDMA systems have better performance than uncoded systems.
