matlab生成m序列的函数 原来那个效率太低，主要是因为实际应用并不需要生成太长的m序列，加入了需求长度，能有效减少运行时间。25级的移位寄存器，运行了一个小时都没有出来一周期，我仅仅需要三千bit而已。改进版：(matlab generate a function of the original m sequence that efficiency is too low, mainly because of the practical application does not require generation of long m sequences, joined the demand for length, can effectively reduce the running time. 25 of the shift register, run for an hour did not come out one cycle, I just need more than 3000 bit. Improved version:)

说明：  MATLAB高阶谱工具箱,方便信号处理工作的完成.(MATLAB toolbox high-end spectrum to facilitate the completion of the signal processing.)

自动检测信号,检测输入的信号设备等等。请根据需要下载(auto detect source!!!!!)

从官网下载的工具箱，用于混沌系统模拟，可画相轨迹，求Lyapunov指数，画分岔图等。(Downloaded the official website of the kit, for analog chaotic system, can be painted with track seeking Lyapunov exponent, Videos bifurcation diagram.)

已知信道状态信息情况下的基于注水法功率分配的OFDM系统 并且和其它系统比较(Known channel state information in case of water injection method based on the OFDM power distribution system and other systems and compare)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)
