用模糊函数法进行时频分析，特别好的程序，本人写论文用到的。(Ambiguity function method using time-frequency analysis, in particular, a good program, I used to write papers.)

document about CDMA in which we have to use CDMA as an alternat of OFDMA and compare the result of the documents

说明：  两种对二阶系统进行参数辨识的最小二乘算法，一种可以直接得到输入输出之间的传递函数，一种可以解出线性的差分方程各系数，再反解得到传递函数。附带的一个二阶系统的模型，可以自行下载导入输入输出数据进行试验。(Two kinds of least square algorithm for parameter identification of second-order system, one can directly get the transfer function between input and output, the other can solve the coefficients of linear difference equation, and then get the transfer function by inverse solution. The attached model of a second-order system can download the input and output data for test.)

pid是个很实用的matlab模块，大家学习啊(pid)

显示关键点，返回值为关键点的坐标，尺度，方向，模值，描述符(return the (x,y),scale,derection,size)

This is coding to analyse the rayleigh fading and its distribution.This is done through Matlab coding

说明：  LTE-A中的AF和DF中继研究，比较有用(LTE-A in the AF and DF relaying research, more useful)
