Aiming at the shortcomings of poor adaptability, high energy consumption and poor data communication performance under the current single-frequency modulation, a wireless mobile laser digital communication system is proposed. The hardware part of the system is mainly composed of modules such as laser communication transmitting, receiving module, encoder, decoder, incremental modulator and spreading device. The software algorithm flow of wireless mobile laser digital communication system is given. According to the data transmitted by the communication system The amount of time slot allocation, and reduce system energy consumption, to ensure data throughput under the premise of wireless mobile laser digital communications to achieve efficient and smooth. Simulation experiments show that the system can balance the network load, reduce system energy consumption and improve communication quality.
