Research on Multipath Channel Performance of Free Space Optical Communication

This research mainly focuses on the free space optical system, through the modeling of data transmission multipath channel in free space optical, and the data transmission process of the free space optical system is explored, the channel fading characteristics in the process of multipath channel transmission are analyzed, and through the calculation of relevant parameters, the dynamic change process of the data transmission multipath channel of the free space optical is explored. The multipath characteristics and the principle of parameter formation in the process of multipath propagation of free space optical data are studied and the multipath dynamic model is established. The main correlative parameters such as path number, delay and fading of wireless multipath channel for data transmission in free space optical are deduced. The path number distribution characteristics of multipath channel are analyzed with stochastic theory, and the dynamic multipath model of wireless transmission in free space optical is established.
