PAPR reduction in OFDM systems

此程序是关于OFDM（正交频分复用）同步中信道响应的程序(This procedure is on the OFDM (Orthogonal Frequency Division Multiplexing) channel synchronization in response to the procedure)

利用梯度投影法解决有约束的目标函数优化问题(Gradient projection method for solving constrained optimization problem objective function)

基于matlab软件对雷达目标进行多普勒参数估计，用到Radon变换(Doppler parameter estimation of radar target based on MATLAB software, using Radon transform )

分支界限法求解整数规划，matlab 分支界限法求解整数规划，matlab(branch and cut with matlab )

在TM波激励下，用矩量法仿真导电柱体的散射，得到电流密度与电荷密度随入射角度变化的规律。(In the TM wave excitation, using the method of moments simulation of the scattering conductive cylinder, get the current density and charge density variation with angle of incidence.)

用粒子群优化算法对三轴稳定航天器姿态控制PD参数进行自动寻优(optimization of PD parameter of attitude controller in spacecraft)

PSO-LSSVM算法的matlab实现，利用PSO算法对LSSVM模型的初始参数求解，以期望得到最好的模型。(PSO-LSSVM algorithm is implemented in matlab, and PSO algorithm is used to solve the initial parameters of LSSVM model in order to get the best model.)

This program is to one-step EEG prediction. it is done by a fuzzy neural network based on a chaotic back propagation training method.

说明：  系统参数辨识，用增广最小二乘算法实现。对书中的程序进行了改进：由于噪声是未知的，虽然我们模拟了系统的随机白噪声，但进行辨识时必须对噪声进行估计，见程序45行和53行。(System parameter identification, with the extended least squares algorithm. Procedures for improving the book: Because the noise is unknown, although we simulate a system of random white noise, but to identify the noise must be estimated, see the program of 45 lines and 53 lines.)
