摘要
为实现通过Notch滤波器处理水声通信指令,论文提出了一种基于多通道Notch滤波器的通信方法,给出了理论推导,建立仿真模型。仿真表明,在接收信噪比大于3dB条件下,接收误码率小于5%,在接收信噪比大于5dB条件下,接收误码率接近为0。
In order to process underwater acoustic communication instructions through Notch filter,this paper presents a com munication method based on multi-channel Notch filter,gives theoretical derivation and establishes simulation model.The simula tion results show that the bit error rate is less than 5%when the received signal-to-noise ratio is greater than 3 dB,and close to 0 when the received signal-to-noise ratio is greater than 5 dB.
