Based on reverse mirror research on lossless transmission technology of modulated signal in wireless spread spectrum communication

In radio spectrum technology, the modulated signals are susceptible to multipath interference, the bit error rate is increased under multipath conditions, and the signal is distorted. The article proposes a modulation signal transmission interference suppression method based on passive time reversal mirror technology in radio spectrum technology, the interference signal is suppressed during transmission to realize lossless transmission. Firstly, a multipath transmission channel model is established in information transmission. Fractional interval balanced technology is used for channel equalization design, and passive time reversal mirror is used for intercode interference suppression and blind signal separation, The lossless transmission of modulated signals is improved by passive time reversal mirror method in wireless spread spectrum communication system. Finally, System performance is tested by simulation method. The channel balance performance is better, the intercode interference is better, and communication symbol error is lower than conventional method.
