摘要

针对水声通信中频谱资源缺陷问题，本文面向全双工水下通信体制，提出了一种基于坐标归零的正交频分复用通信方法。该方法从水声通信编码角度对本地自干扰进行了有效抑制，并通过仿真和水池实验进行了验证。水池实验结果表明：在-45 dB的信干比下，算法可在带内实现远端信号的精确提取，误码率降至10

-3

。该方法可与多种干扰抵消方法进行有效融合，形成新型多域联合自干扰抵消方法，进一步突破自干扰抵消上限，为带内全双工水声通信工程应用提供了有利的技术支撑。

Abstract

This paper addresses the problem of spectrum resource defects in underwater acoustic communication. To this end

an orthogonal frequency-division multiplexing (OFDM) communication method based on coordinate zeroing for a full-duplex underwater communication system is proposed. This method effectively suppresses local self-interference from the perspective of underwater acoustic communication coding. The algorithm was verified by simulation and pool experiments. The pool experiments showed that for a signal-to-interference ratio of -45 dB

the algorithm accurately extracted the far-end signal in the band

and the bit error rate decreased to 10

-3

. Moreover

this method can be effectively integrated with various interference cancellation methods to form a new multidomain joint self-interference cancellation method. This new method further breaks through the upper limit of self-interference cancellation and provides favorable technical support for in-band full-duplex underwater acoustic communication engineering applications.
