this file is related to qpsk quadrature phase shift keying mod. in fading channel..which is helpful in desgining a channel with qpsk mod technique

基于matlab将商标与文字分割，选定阀值，先进行次分割，在进一步优化(Matlab-based trademarks and text segmentation, the selected threshold, the first for sub-division, in further optimization)

多尺度熵matlab程序，很好用，里边有注释，适合初学者(Multiscale entropy matlab program, easy to use, there are notes, suitable for beginners)

说明：  基于MATLAB的一个电力系统潮流分析程序，效果不错(A MATLAB-based power flow analysis program, good results)

说明：  对离散数字信号实现QPSK调制，输出调制后的信号(Implementation of discrete digital signals QPSK modulation, the modulated signal output)

说明：  bP网络,网络的训练算法是反向传播算法，即神经元的链接权重的训练是从最后一层(BP network, network training algorithm is BP back propagation algorithm, i.e., neurons in the link weight training is from the last layer)

基于MATLAB的QPSK调制程序，简单易懂(QPSK demodulation based on MATLAB program, easy to understand)

用matlab实现FIR滤波器的带通滤波器设计，简单实用(Matlab FIR filter band-pass filter design, simple and practical)

使用传统的几种算法来形成自适应波束，包括最大信噪比准则（MSNR），线性约束最小方差（LCMV）和最小均方误差准则（MMSE）等。(The traditional algorithms are used to form adaptive beams, including maximum signal-to-noise ratio (MSNR), linear constrained minimum variance (LCMV), and minimum mean square error criterion (MMSE).)
