一种变结构抗梳状谱干扰的通信体制

摘要

当代的电磁环境对通信抗干扰的要求不断提高,必须不断探索更有效的抗干扰方法以提高通信性能.在此背景下针对高斯信道提出一种变结构抗常见梳状谱干扰的通信体制,该方法主要利用双极性脉冲扩展二元相移键控调制的优势,在不同的信道环境下选择不同的调制方式并调节相应的调制参数.通过仿真分析可以预见,在梳状谱干扰通信信道下,该通信体制能够以较小的代价获得较好的抗干扰效果.%The requirement for anti-interference capability in current electromagnetic environment is increasingly high,which needs more effective anti-interference methods to improve the communication performance constantly.A new variable structure communication scheme in Gaussian channel is proposed to solve this problem,which is mainly designed for common comb spectrum interference.It utilizes the advantages of bipolar pulse EBPSK modulation with various waveforms used under different channel environments.The simulation result indicates that better communication effects can be achieved with less cost.
