It's well known that underwater acoustic channel is a coherent multi-path channel, which brings difficulties in signal processing because of the complexity of the received signal sequence.

众所周知，水下声信道是相干多途信道，信号在信道中的多径传播使得接收信号序列复杂化，因而极大地增加了信号处理的难度。

Secondly, power line noise channel and multi-path channel optimization modeling techniques based on artificial neural network are proposed.

其次，提出了电力线噪声信道和多径信道的神经网络优化建模方法。

Compared with single channel single - path routing scheme and multi - path routing scheme, the results of simulation show that this model has better network performance.

仿真结果表明，相对单通道单路径路由及多路径路由本模型能更好的改善网络性能。
