The figure shows the graph of the analytical BER, simulated against the mean SNR to show the impact of DF MIMO-RF / FSO cooperative systems using GC-LDPC codes for conditions of strong atmospheric turbulence.
This figure also shows the advantage of using mixed DF MIMO-RF / FSO cooperative systems using GC-LDPC codes. It is clearly seen that the performance of MIMO-RF/FSO systems is better than that of end-to-end (RF/FSO) systems. In addition, one can also see the impact of the number of transmitting and receiving antennas on the performance of the MIMO-RF / FSO system.
