Abstract

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.

基于反向镜像的无线扩频通信中调制信号无损传输技术研究

在无线电频谱技术中，调制信号容易受到多径干扰，多径条件下误码率增加，信号失真。本文提出了一种基于无线电频谱技术中无源时间反转镜像技术的调制信号传输干扰抑制方法，在传输过程中对干扰信号进行抑制，实现无损传输。首先，建立了信息传输中的多径传输通道模型。采用分数阶间隔平衡技术进行信道均衡设计，采用无源时间反转镜进行码间干扰抑制和盲信号分离，采用无源时间反转镜方法提高了无线扩频通信系统中调制信号的无损传输。最后，通过仿真方法对系统性能进行了测试。与传统方法相比，该方法具有更好的信道平衡性能、更好的码间干扰和更低的通信符号误差。
