Abstract

Various approaches have been put forward to reduce impairments affected by turbulence fading in free-space optical(FSO) communication systems. In this paper ,We study the ASEP (average slot error probability )and APEP(average packet error probability) performance of PPMs approximately in optimal detection threshold while channel state information(CSI) is best estimated in receiver. In our framework , We mainly focus the weak turbulence with log normal fading and these two probability(ASEP and APEP) are calculated by the method proposed by Holzman. Furthermore, ASEP and APEP are simulated to study how the performance metrics are affected by the atmospheric conditions and other PPMs parameters such as modulation order M , numbers of slots m, pulses q parameters and numbers for information bits N.
