Effect of phase noise on bit error rate performance of BPSK subcarrier intensity modulated wireless optical systems: Simulation
Project: Advanced Techniques for Efficient Use of Spectrum in Wireless Systems (MESTD - 32028)
Abstract
In this paper, the bit error rate (BER) performance of binary phase-shift keying (BPSK)-based subcarrier intensity modulated (SIM) free space optical (FSO) communication system is analyzed. The influence of imperfect reference signal recovery on BER values in detecting PSK SIM signals transmitted over Gamma-Gamma turbulence channel was determined by Monte Carlo simulations. Simulations results indicate that imperfect reference signal recovery causes the irreducible error floor that is an important system characteristic.
