摘要
针对DPIM调制与RS码结合中的矛盾,分析了一种DPIM的改进形式—FLPIM与RS码结合的差错性能。结果表明,FLPIM峰值光功率相等时,在高斯信道中可获得约2-4dB的编码增益,在弱湍流信道中可获得约2-4dB的编码增益。
In order to resolve the contradiction between RS code and DPIM,FLPIM is introduced as the better modulation.And discuss the error performance of different type of RS code under FLPIM in Gauss channel and weak turbulence channel when the peak power of FLPIM is equal.The simulated results indicate that the error performances can earn 2-4dB gain under Gauss channel weak turbulence channel.
