可以简单的实现快速傅里叶变换，这只是部分的，等开通了账号再把其他的上传上来(Can simply fast Fourier transform)

Writes frequencies for different notes in matlab, and plays the first two lines of the Beatles Daytripper.

基于PCA的人脸识别 Matlab代码 两种方法 KL 和kernel(PCA-based face recognition Matlab code)

说明：  在matlab中实现高斯序列，三角序列，反三角序列等，分析其频谱特性(In matlab to achieve Gaussian sequence, triangular series, the anti-triangular sequence and so on, to analyze its spectrum characteristics)

比较好的学习matlab的资料，希望能够帮助有用的人(Learning matlab better information useful to help people)

自适应回波抵消算法 LMS算法 NLMS算法(Adaptive echo cancellation algorithm)

package_emd,非常重要的工具箱，用于EMD的数字信号分解(package_emd, a very important kit for digital signal decomposition EMD)

simulation modulate & demod QPSK

16qam 换句话说,信号可能仍然是 探测到,但以较低的质量。这是通常所说 对软失败。幸运的是,新的传(16qam simulink ser mimo one of the receive chains fail, and the other receive chain is operational, then the performance loss is on the order of the diversity gain. In other words, the signal may still be detected, but with inferior quality. This is commonly referred to as soft failure. Fortunately, the new transmit diversity scheme provides the same soft failure. To)
