通信原理课程做的大作业，关于正交调制的。(communication theory courses do the work, on the orthogonal modulation.)

Matlab实用小程序实例合集第一部分，都是一些完成特定功能的小程序，很适合新手朋友(Practical examples of Matlab collection first part of the program, are some of the specific features of the completion of a small program, it is suitable for novice friend)

matlab下用小波去除随机噪声的一个例子，希望对大家有用(matlab remove the random noise using wavelet under an example, we hope to be useful)

学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)
