基于MATLAB软件仿真设计FIR滤波器，然后对噪声信号进行去噪，从而改善语音信号的质量。本文滤波器设计的方法则是采用简单的窗函数（凯撒窗）来设计的，并利用MATLAB作为编程工具完成一些数据的计算以及绘制出去噪前后的时域图和频谱图。通过对比去噪前后的时域图和频谱图，或者通过生成的声音文件，分析说明出滤波器设计的正确性。(The FIR filter is designed based on MATLAB software, and then the noise signal is de noised to improve the quality of speech signal. The method of designing the filter in this paper is designed by using a simple window function (Kai Sachuang), and using MATLAB as a programming tool to complete the calculation of some data and to draw the time domain diagram and spectrum map before and after the denoising. By comparing the time domain and frequency spectrum before and after the noise elimination, or through the generated sound files, the correctness of the filter design is illustrated.)
