Motivated by the applications of RF/FSO, MIMORF/FSO systems and taking into account the limitations of the existing literature, we study the performance of cooperative RF / FSO and MIMO RF / FSO systems assisted by DF relay based on error correcting codes particularly the globally linked LDPC codes (GC-LDPC).
We also used PPM to modulate the data, we assume that FSO links follow the Gamma-Gamma distribution, while MIMO-RF links follow Rayleigh fading. We will also compare the use of GC-LDPC in mixed MIMORF / FSO communication versus SC-LDPC and QC-LDPC codes.
