利用duffing振子检测微弱信号频率的matlab程序。可以检测与周期策动力频率相差0.03之内的微弱信号频率。信噪比达到-68db(use Duffing oscillator frequency detection of weak signals in Matlab procedures. Can be detected with the cycle driven frequency difference of 0.03 within the weak signal frequency. Signal-to-noise ratio-68db)

Calculation of Chang E III whereabouts time

good resource code for people to get better performance.such as ssim,rmse etc.

基于FPGA的快速傅里叶变换。使用ISE软件以及MATLAB验证。(FFT based on FPGA)

此函数为在matlab软件编写的图像合并函数。(this is a m function for two image merging.)

ofdma的一个简单的收发程序采用QPSK调制噪声是高斯白噪声(A simple transceiver of ofdma program using QPSK modulation noise is gaussian white noise)

对振动信号进行小波包分解，并以小波包的节点能量作为特征进行了提取。(The vibration signal is decomposed by wavelet packet, and the node energy of wavelet packet is taken as the feature to extract the vibration signal.)

以高斯函数为载波的PPM调制解调，及于理想误码率曲线相比较的误码率曲线(Gaussian function of PPM modulation and demodulation of the carrier, and the desired BER curves compared to BER curves)

RASTA-PLP Speaker Identification

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单(This program is the most basic particle swarm optimization algorithm, using Matlab to achieve, is very simple)
