BER Analysis of Hybrid LPPM-POLSK-SIM Over Double Generalized Gamma Distribution Incorporating Zero Boresight Pointing Error

Free Space Optical (FSO) communication transmits the information using light propagation in the free space permitting optical connectivity. So, there is no necessity for optical fiber cables. FSO provides the solution for the requirement of large bandwidth and high speed for data transmission. Here, we use hybrid modulation scheme LPPM-POLSK-SIM using Double GG distribution in FSO in presence of a generalized pointing error model consisting of normalized spatial jitter effect as well as zero boresight displacement effect. Afterwards, we look at how it performs in terms of average bit error rate for plane waves under weak, moderate and strong turbulent conditions. For all values of L, simulation findings demonstrate that BER is less with least value of L and under weak turbulence conditions than with a moderate or strong turbulence condition.
