用MATLAB实现QPSK在AWGN信道的调制(Using MATLAB to achieve QPSK modulation in AWGN channel)

ofdm发送端和接收端，根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。(ofdm sending end and receiving end, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives.)

因子分析可在许多变量中找出隐藏的具有代表性的因子。将相同本质的变量归入一个因子，可减少变量的数目，还可检验变量间关系的假设。(Factor analysis can be found in many variables hidden with a representative factor. The same nature of the variables included in a factor, can reduce the number of variables, but also to test the relationship between the hypothesis.)

Algorith PCA in Matlab. The example is basic, with random data
