中文说明： 现代信号处理中谱估计在matlab中的使用，最终的权值矩阵就是滤波器的系数，最大信噪比的独立分量分析算法，实现了对10个数字音的识别程序有借鉴意义哦，实现串口的数据采集。
English Description：
Modern spectral estimation using MATLAB in signal processing, the final weighting coefficients of the matrix is to filter, maximum SNR algorithm of independent component analysis realized for 10 digital voice recognition programs have significance to realize serial data acquisition.
