End-to-end performance of DF multihop hybrid RF/FSO system using MPPM coding and MIMO technique under dependent GG turbulence channels

<p><span>The paper presents a BER analysis for hybrid Radio Frequency/multihop Free Space Optics, known as RF/FSO, communication system benefiting from Multiple Input Multiple Output (MIMO) configuration but impaired by Gamma-Gamma, known as GG, turbulence. Authors deploy Multiple Pulse Position Modulation, known as M-PPM, like a signaling technique. Furthermore, the exact as well as approximated amounts of Symbol-Error Rates, known...
