Abstract
A novel free space optical (FSO) wireless communication system is proposed very recently utilizing acousto optical modulator (AOM) to externally modulate the laser beam [1]. The idea is to control the diffracted angle of a laser beam incident to an AOM through varying the acoustic frequency propagating inside the AOM. The receiver with multiple photo diodes, spatially distributed and aligned to the preplanned diffracted angles, receive the laser signal and retrieve the transmitted bits. In this paper, we study the performance of AOM–FSO system over negative exponential turbulent channel. A closed-form expression for the average bit error probability is derived and shown to be precise over wide range of channel and system parameters. The performance of the system is compared to the ideal case of no fading and log normal channel.
