中文说明：意信号卷积的运算,并且绘制图象，完整的基于HMM的语音识别系统，代码里有很完整的注释和解释，包括最后计算压缩图像的峰值信噪比和压缩效果的源码,基于matlab平台实现,这是一个好用的频偏估计算法的matlab仿真程序。
English Description：
Signal convolution operation, and draw images and complete HMM based speech recognition systems, the code is very complete annotated and explained, including the final calculation of compressed images of the peak signal to noise ratio and compression effect of the source code, based on MATLAB platform. This is a good use of frequency offset estimation algorithm matlab simulation program.
