Abstract

This paper investigates the performance of a differential phase shift keying subcarrier intensity modulation (DPSK-SIM) based free space optical (FSO) communication system over strong atmospheric turbulence channel with pointing errors. Novel closed-form analytical expressions are derived for average bit error rate (BER), channel capacity and outage probability. The simulated results for average BER, channel capacity and outage probability of DPSK-SIM modulation technique is analyzed with 2D and 3D plots.
