Abstract
An anti-co-frequency interference suppression method for wireless spread spectrum communication based on equivalent low-pass time-varying pulse modulation technology is proposed. The anti-co-frequency interference system for wireless spread spectrum communication is designed based on Internet of things technology, and the multi-path channel model for wireless spread spectrum communication is constructed. The Doppler spread technique is used to design the channel equalization of wireless spread spectrum communication system. The equivalent low-pass time-varying pulse modulation method is used to suppress the same-frequency interference and blind source separation. Improve the lossless transmission ability of the Internet of things (IoT) transmission signal in the wireless spread spectrum communication system. The simulation results show that this method is used to design the wireless spread spectrum communication system and the co-frequency interference is effectively suppressed and the bit error rate of communication is lower than that of the traditional method.
