Digital Signal Processing using Matlab

DK-SVD，CVPR文章 Discriminative K-SVD dictionary learning for face recognition 源码，效果好于原始SRC(DK-SVD，the source code of CVPR paper Discriminative K-SVD dictionary learning for face recognition, its has a better performance than the classical SRC classifier )

Spread spectrum techniques can be very useful to overcome the communication problems like security and efficient usage of power. In this technique, the information signal to be transmitted is multiplied by the PN code (This is the general case and it can be any kind of sequence.),called spreading code signal. The signal which is obtained after the multiplication of PN code is called spread signal which is then transmitted.

关于粒子群优化的好文章，文章的PSO说话的很详细，希望能给新手一些帮助。(About Particle Swarm Optimization a good article, the article PSO speak in great detail, I hope to give beginners some help.)

简单的人工鱼群算法的matlab源码，希望对大家有所帮助，有问题可以交流，谢谢指正.(Artificial fish swarm algorithm matlab source code, we want to help, the problem can exchange, thank you correct me.)

实现心电信号傅里叶变换处理、并显示原信号和处理后的信号(realized the FFT of ECG, and display the results)

This collection of MATLAB software contains implementations of several Algebraic Iterative Reconstruction methods for discretizations of inverse problems.

信号检测很有用的参考资料，很全。非常适合自学者(signal processing ,good for newer)
