Abstract
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, the symbol of optical communication signal to be transmitted is divided into several blocks. Several subcarriers are formed after series–parallel conversion. Symbols are modulated onto these orthogonal subcarriers. The modulation signal of optical communication in OFDM network is formed by superposition, and the multi-carrier modulation of optical communication signal is completed. The stable transmission of optical communication signal after multi-carrier modulation is realized using DCHP protocol. By introducing the data fusion technology of neural network, a deep fusion model of optical communication channel based on BP neural network is established. To realize the deep integration of optical communication channels, a hierarchical routing protocol is proposed. The experimental results show that this method can reduce the transmission delay and energy consumption of optical communication signals. It can solve the problems in optical communication and has high application value in real life.
