摘要
讨论了m序列水声扩频谱通信的若干关键技术 ,给出了一种m伪随机序列信道编码设计 ,提出了相干重置相乘信道均衡算法 ,并在此基础上给出包络相关解码处理器 .仿真表明 ,相干重置相乘信道均衡器 ,提高了处理增益 ,而且对信道的估计误差不敏感 .
We discussed some key techniques of m sequence used in spread sepectrum underwater acoustic communication.A UAC channel coding schedule was presented.An equalizer algorithm was developed,and the envelope correlation decoding approach was also discussed.Simulations show that the equalizer is not only unsensitive to the estimated error of underwater acoustic channel,but also can detect signals in high noise environments.
