此电子资料为小波与傅里叶分析基础，里面主要讲解有关小波和傅里叶的理论知识，和一些相关的应用。此书可以实践在实验上用matlab来实现。(This electronic data base wavelet and Fourier analysis, which is mainly explain the wavelet and Fourier s theory of knowledge, and a number of related applications. This book can be practiced using matlab to achieve experimentally.)

实验四 数字解调与眼图 1. 验证2DPSK 相干解调原理。 2. 验证2FSK 过零检测解调原理。 (Four digital demodulation experiment with eye diagrams 1. verify the 2DPSK coherent demodulation. 2. Verify 2FSK zero-crossing detection and demodulation principle.)

分别用非参数化谱估计中的直接法，间接法和加窗法对离散随机过程的已零均值化的N个数据样本估计了离散信号的谱密度。(Were non-parametric spectral estimation of the direct method, indirect method and windowing method, discrete stochastic process has zero mean the data of the N-sample estimates of the spectral density of discrete signals.)

这个一个关于Matlab的参考资料，包涵文件IO，tex字符等等，可做参考(This is a Matlab reference include file IO, tex characters, etc., can refer to)

In this code, the BER performance of a system which uses sparse channel estimation is compared with a system which uses LSE channel estimation. It is shown that using sparse technique improves the performance of the system

对目标进行识别，采用直方图的方法，结合matlab和c语言(Target identification, using the histogram method, combined with matlab and c language)
