化学化工中的数学方法及MATLAB实现代码(Chemistry and Chemical Engineering and Math in MATLAB code implementation)

说明：  在matlab中，采用RLS算法的自适用滤波器对信号进行均衡处理的源码。(in Matlab, using RLS algorithm applies the filter right from the signal of a balanced source.)

详细描述了关于几个同时说话人语音分离的情况，其中包括了原代码和测试语音，测试结果表明分离效果很好，能够区分不同人说话的语音，明显提高语音识别率。其中的参考论文在readme中。(A detailed description about several while speaking voice separate conditions, including the original code and test speech, test results show that the effect is very good separation between different people speak of speech recognition, obviously improved pronunciation. One of the reference in the readme.)

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)
