Performance Comparison of Modulation Schemes for Atmospheric Optical Communication

  • The performances of modulation schemes,OOK(on off key),PPM(pulse position modulation),DPPM(differential pulse position modulation) and DPIM(digital pulse interval modulation),used in optical communication over the atmospheric turbulence channel were analyzed and compared in terms of packet error rate(PER) and bandwidth efficiency.In terms of PER,DPIM is the best followed by PPM and DPPM,and OOK is the worst.With regard to bandwidth efficiency,PPM is desirable with a small modulation parameter,and DPPM and DPIM are good with a large modulation parameter.All these schemes,except OOK,require a small laser power.
