摘要
本文根据某水域浅海表面声信道的衰减吸收特点,确定通信系统方案,并且进行了试验;利用时域宽带波束形成、归一化、加窗滤波等算法进行信号处理和解调译码。试验结果表明,该方法可以完成湖上一定距离的水声通信,具有一定应用前景。
According to the attenuation of a shallow sea waters surface acoustic absorption characteristics of the channel, the paper decides and tests the communication system solutions. By using the broadband time-domain beam forming, normalizing and windowed filtering algorithms for signal process and demodulation decoding. The test results show that this method can realize underwater acoustic communication for a certain distance on sea,which has a certain application prospect.
