This is about QPSK modulation in simulink.

一个关于，神经网络预测投资对GPD的影响的实例(A neural network to predict, the influence of GPD investment)

This is a journal that you need to build a AAC Compression

非常好的matlab代码，欢迎下载分享学习！！！(this is a very good！！！！！！！！！)

matlab 用PSO 解决背包问题 (matlab solve the knapsack problem with PSO)

一种新的EMD改进算法，可以结合其他的解调技术，比如1.5维谱，最小熵解卷积，奇异值差分谱，小波能量谱等。(EMD, a new improved algorithm can refer to.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

As was pointed out to investigate the behavior of synchronous generator using a simple model (model steady state) is not sufficient so that the equations obtained in the dq. For simulation models to make them as equations of state:
