huffman coding and huffman decoding

对语音信号进行高通、低通、带通滤波器处理(voice lowpass highpass bandpass)

this matlab codes for using in communication systems this codes very important in communication systems.

这是一个用matlab写的小波域HMM进行一维信号处理的程序(This is a matlab written using wavelet-domain HMM for one-dimensional signal processing procedures)

GUI界面例子 具体关于数值分析的很多，也很齐全，有用(GUI interface on the numerical analysis of specific examples of the many)

维纳滤波函数的MATLAB程序，消除信号中的噪声的一个程序，(Wiener filter function of the MATLAB program)

地球物理专业的地震波数值模拟程序，matlab编写，大家交流学习。。(Geophysics, seismic wave numerical simulation program, matlab prepared to share learning. .)

matlab coce for generate MSK modulation.

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.)

本程序为地球直角坐标转球面做的程序，本程序考虑到了不同的地球模型，采用了对应于不同模型的参数(This procedure turn spherical Earth Cartesian coordinate the program, the program taking into account the different Earth model using the parameters corresponding to the different models)
