无线光通信中几种调制方式的性能比较

Performance Comparison of Various Pulse Position Modulation for Pptical Wireless Communication

应用在无线激光通信系统中的调制方式有多种。该文详细地分析了开关键控(OOK)、脉冲位置调制(PPM)、双头脉冲间隔调制(DHPIM)和双脉冲间隔调制(DPPIM)等调制方式的符号结构、带宽需求、平均发射功率和误时隙率等性能,通过分析比较得出DHPIM的综合性能最佳,更适合于无线光通信系统。

There are a lot of modulation schemes applied on wireless laser communication. The main purpose of this paper is to analyse and compare the performance of symbol structure,bandwidth requirement,average transmit power and slot error rate about the modulation schemes of OOK,PPM,DHPIM,DPPIM.The simulation results show that the DHPIM is fitter for the optical wireless communication.
