使用matlab模拟OFDM信号接收全过程。(OFDM signal using matlab simulation of the entire process of receiving.)

说明：  对rosenstein求解最大李雅普诺夫指数算法,实现成功(Rosenstein solving of the largest Lyapunov exponent algorithm, to achieve successful)

说明：  卡尔曼滤波器matlab源码，初学者可以作为参考，也可以直接应用(Kalman filter matlab source)

Kalman filter for RSSI signals

读取、绘制Tek示波器保存的MathCAD格式数据文件，扩展名为.ISF(Read data from MATHCAD file generated by TEK oscilloscope with file extension .ISF)

说明：  这个程序是使用MATLAB对ofdm中的压缩扩张技术降低PAPR技术的仿真，程序仿了不同u值下的对PAPR的降低程度不同(that is a simulation of papr using matlab ,it is using u_law companding)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

用改进的PTS方法降低OFDM信号中高PAPR的MATLAB仿真源代码，(A Modified Genetic Algorithm PTS Technique for PAPR Reduction in OFDM Systems )

频率同步算法的时域方法。利用两个连续重复的符号计算频率误差估算。(Frequency synchronization algorithm for time-domain method. The use of two consecutive duplication of symbolic computation to estimate frequency error.)
