matlab 实现数据的短时傅里叶变换 自己测试通过(short time Fourier transform matlab achieve data test by)

QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

本程序利用Matlab软件仿真了QPSK+瑞利信道及高斯信道，对比分析结果。(This procedure used Matlab software simulation QPSK+ the Rayleigh channel and the Gauss channel, the contrastive analysis result.)

本论文详细分析了LTE网络的上行链路的闭环功率控制，特别的详细，是国外的一篇博士论文。(LTE Uplink closed power controll)

dct与小波压缩，适用于毕业设计和论文呢(dct and wavelet compression)

简单介绍了用工具MATLAB编写元胞自动机，其中有简单的设计思路，源代码。(A brief written using MATLAB tools of cellular automata, which have a simple design idea, the source code.)

说明：  寻找三次样条多项式需要求解大量的线性方程。实际上，给定N个断点，就要寻找N-1个三次多项式，每个多项式有4个未知系数。这样，所求解的方程组包含有4*(N-1)个未知数。把每个三次多项式列成特殊形式，并且运用各种约束，通过求解N个具有N个未知系数的方程组，就能确定三次多项式。 (find cubic spline solving polynomial need a lot of linear equations. In fact, given N breakpoints, it is necessary to look for N-1 cubic polynomial, each with four polynomial coefficients unknown. Thus, by solving the equations contain 4* (N-1) unknown. Each cubic polynomial Timing special form, and use of various constraints, by solving N with N unknown coefficient equations, we can identify three polynomial.)
