Aiming at the problem of short transmission distance and large loss in free-space transmission of optical communication data, a research method of optical communication data transmission channel based on digital shadow model and multipath effect is proposed. The large-scale and small-scale fading characteristics of free-space optical wireless transmission channel are described using logarithmic shadow...
To solve the problems of long transmission delay and high energy consumption caused by the number of optical communication signals and sub-nodes in the network, a deep fusion method of optical communication channel based on multi-carrier modulation is proposed in this paper. Based on noise modeling of wireless optical communication network and attenuation modeling of optical communication signal,...
