文件是matlab环境，用于电力分析计算和仿真(Document is a matlab environment, used in power analysis and calculation and simulation)

arnoldi算法解大规模线性方程组，可以解的方程是可以非对称(arnoldi algorithm for solving large-scale linear equations, possible solutions to the equation is non-symmetrical)

用Matlab实现滤波器模型与仿真的功能(Achieved with the Matlab function filter model and simulation)

完成一个利用矩形信号星座图的M=16的QAM通信系统的Monte Carlo仿真(the matlab source code of QAM)

基于功率谱相减法的语音消噪，采用动态阈值法(Power spectrum subtraction based denoising of speech using dynamic threshold method)

Calculating SNR and BER to System MIMO using SVD and receiver shaping.

这个主要是提取特征之后利用LDA线性分析来进行多类分类，采用一对多策略。本例中是有六个类别(multiple patterns recognition using LDA, which is about one-vs-rest)

C-均值聚类 BP神经网络信号分析与处理方法，对模拟产生的数据样本进行训(C-means clustering analysis and BP neural network signal processing method, the simulated data generated training samples)

You can learn BPSK modulation in OFDM Systems BPSK means binary phase shift keying modulation. Basically OFDM uses fft/ifft modulation. and add cyclic shift and remove to cancel inter-symbol-interference.

DSP算法参考，包括FFT，ICA等算法，非常实用的参考。(DSP algorithm for reference, including the FFT, ICA and other algorithms, a very useful reference.)
