spider，很好用的模式识别工具箱，里面有各种分类工具，从有监督学习到无监督学习，从模型选择到参数选择。而且也将各个方法封装成类，使用方便。(spider, good use of pattern recognition toolbox, there are various classification tools, from supervised learning to unsupervised learning, choose Preferences from the model. But also the various methods into a class package, easy to use.)

EMD分解，有效经验模式分解，有效经验模式分解，有效经验模式分解(EMD decomposition，EMD decomposition，EMD decomposition，EMD decomposition)

说明：  QPSK详细调制解调的源码，包括整个流程．(QPSK modulation and demodulation of the source in detail, including the entire process.)

qpsk transmiter with qpska modulator QPSK is a method for transmitting digital information across an analog channel.Data bits are grouped into pairs, and each pair is represented by a particular waveform, called a symbol, to be sent across the channel after modulating the carrier.
