摘要

针对传统正交频分复用系统对部分频带干扰敏感的问题

提出了一种结合线性星座预编码的部分频带干扰抑制方法.该方法通过估计受到强干扰影响的子载波位置并将该类子载波接收信号置零来构造不含强干扰分量的判决统计量.利用线性星座预编码优异的分集特性

将该统计量用于检测可恢复发送数据且消除强干扰的影响.相对于已有的编码正交频分复用及载波干涉正交频分复用两种干扰抑制方案

该方法对部分频带干扰有更好的鲁棒性

在强干扰下没有误码率底限.仿真结果表明

当信干比为-10 dB时

该方法的误码率随信噪比增加迅速减小

在信噪比达到20 dB时误码率可降至10

-3

Abstract

Aiming at the drawback of sensitivity to partial-band jamming in conventional orthogonal frequency division multiplexing systems

a partial-band jamming rejection method combined with linear constellation precoding was proposed. A new decision statistic excluding high-power interference was build through setting the signals from the severely jammed sub-carriers to zeros after estimating the indices of these sub-carriers. Then the new decision statistic was adopted to recover the transmitted data thanks to the remarkable diversity of linear constellation precoding. The effect of the strong jamming was also eliminated. Compared to the existing anti-jamming schemes

coded orthogonal frequency division multiplexing and carrier interferometry orthogonal frequency division multiplexing

the pr

oposed method demonstrated better robustness to partial-band jamming and the floor of bit error rate under strong jamming was removed. Simulation results showed that

the bit error rate curve of the proposed method has a waterfall shape when signal-interference-ratio is -10 dB. The bit error rate could achieve 10

-3

while signal-noise-ratio is 20dB.
