经典的LDA特征选择算法，用matlab实现，包括数据集(LDA classic feature selection algorithm, using matlab to achieve, including a data set)

matlab中尝试修改坐标系的方法，采用极坐标(matlab try to modify the method of coordinate system, using polar coordinates)

直接序列扩频代码。。。包括15位的伪随机序列生成器(DSSS communication system s simulation code,include 15-bit persudo code generator)

采集到的50Hz电源信号送至信号处理器作为参考信号，该参考信号在信号处理器中需经HILBERT变换变成两路正交正余弦信号X1、X2，然后采用自适应滤波器算法滤掉有用信号中的50Hz信号。(Collected 50Hz power signal to the signal processor as a reference signal, the reference signal in the signal processor requires HILBERT transform into two orthogonal cosine signal is X1, X2, and then filter out the use of adaptive filter algorithm useful signal in the 50Hz signal.)
