Performance Analysis of Elastic MIMO-RF/FSO Communication Over Lutz Model with LDPC

Elastic radio frequency (RF)/ free space optical (FSO) system is a promising solution to access high reliability and quality of performance in satellite-ground communications. It is introduced as a reconfigurable system since RF and FSO links suffer from some unfavorable atmospheric conditions individually. Elastic RF/FSO system has considered RF as a back-up link while FSO stops working due to aforementioned destructive effects. This work has analyzed the performance of two kinds of channel coding schemes named low density parity check (LDPC) and space time block codes (STBC) the former is applied to provide coding gain and the latter to provide spatial diversity over Lutz model considered as a statistical model in RF communication. Finally, the bit error rate (BER) performance of coding schemes has been evaluated over Lutz model with Rayleigh and Rician fading distributions. Simulation results demonstrate a considerable BER reduction even in low signal to noise ratios particularly when FSO meets undesirable atmospheric effects.
