In wireless spread spectrum communication in the modulation signal transmission is easily affected by the multi-path effect of multipath channel generated intersymbol interference

the error increases

the signal transmission distortion

a modulation signal transmission wireless spread spectrum communication system passive time reversal technique stem interference suppression method based on lossless transmission of communication signals

the first building the multipath channel model of wireless spread spectrum communication

channel equalization design using fractionally spaced equalization technology

the passive time reversal mirror method to suppress intersymbol interference and blind source separation

improve the ability of modulation signal lossless transmission wireless spread spectrum communication system. Finally

through the simulation experiment of performance test results show that by using this method in the design of wireless spread spectrum communication system

channel equalization performance better

intersymbol interference can be effectively suppressed

the communication error rate is lower than the traditional method.
