中文说明：有均匀线阵的CRB曲线，最终的权值矩阵就是滤波器的系数，主同步信号PSS在时域上的相关仿真，有PMUSIC 校正前和校正后的比较，基于人工神经网络的常用数字信号调制，实现了对10个数字音的识别程。
English Description：
Uniform linear array of CRB curve, final weight matrix is that of the filter coefficients, PSS main synchronizing signal in the time domain simulation, correction PMUSIC before and after correction of the comparison, commonly used digital signal modulation based on artificial neural network, the realization of the 10 digital audio recognition process.
