The basic principle of spread spectrum communication is introduced, and the anti-interference characteristics of spread spectrum communication are analyzed. On this basis, the basic structure of power line carrier communication system is expounded, and a method of using single-chip microcomputer software programming to realize power line carrier spread spectrum communication is proposed. The computer simulation is used to analyze the change of bit error rate under different signal-to-noise ratio conditions, and the results show that the proposed method can improve the communication quality and reduce the bit error rate through the implementation of software algorithms without increasing hardware costs.
