lte系统中turbo研究,信道编码技术以及matlab仿真后的比较(LTE and TURBO)

基于小波的音频水印嵌入代码。采用DB1小波(Wavelet-based audio watermark embedding code. Using wavelet DB1)

As digital computers cannot generate true random numbers. So a pseudo random number generator must have uncorrelated sequences, long period, uniformity and efficiency. ‘myrand.m’ has pass the chi square test for uniform distribution.

Create graphs of 3 dimensional logarithmic of a function named F(Theta,Phi), theta the elevation angle and phi the rotational angle. Converts to Cartesian coordinates and plots a surface plot with color pattern radiating from the origin.

基于纹理特征的图像检索源码，通过双树复小波进行纹理特征提取(Texture-based image retrieval source, through the dual tree complex wavelet texture feature extraction)

一次调频 matlab/simulink仿真模型(Primary Frequency matlab/simulink model)

求解微分方程，这个压缩包里包括了：1. 欧拉公式2. 休恩公式3.四阶龙格-库塔公式三种方法(matlab)

采样定理的验证，即采样信号的频率大于等于原信号频率的两倍时才能准确的恢复原信号(Verification sampling theorem, the sampling frequency of the signal frequency is greater than or equal to twice the original signal in order to accurately restore the original signal)

将toeplitz矩阵作为压缩感知测量矩阵，并对其进行性能评估。(Toeplitz matrix as the measurement of compressed sensing matrix, and its performance evaluation.)
