OFDM_PAPR_reductn

一种基于回波相关的无源合成孔径雷达成像方法(An Echo-correlation Based Passive Imaging Method for Synthetic Aperture Radar)

基于DFT的快速DOA估计，适合于相干信号源和非相干信号源(DFT-based fast DOA estimation, is suitable for coherent signal source and non-coherent signal source)

此程序参照了IEEE 802.11a ，使用了52个子载波。理论期望papr为52.但是由加扰器的存在，所有子载波很难一直的调制(Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely. )

说明：  利用虚拟力算法 求出覆盖率最大的部署方式(The virtual force algorithm is used to find the deployment mode with maximum coverage)

说明：  包括了基于能量检测方法的信号检测，其中采用M2M4算法进行了噪声方差估计。本程序为MATLAB仿真，可以直接应用。(this program contains the energy-based signal detection method. and the M2M4 method is used to estimate the variance of the background noise.)

一种扩展卡尔曼滤波算法源程序 简单易懂 功能强大(an extended Kalman filter algorithm source code is simple to understand the powerful)

说明：  有关神经网络理论与matlab r2007的实例与应用，都是教程，(Related to neural network theory and matlab r2007 and application examples are tutorials,)

图像截图完成一个简单的多媒体应用程序，包含：多媒体信息的获取、处理、展现三个基本过程。(this is a snapshot code)

function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

MATLAB与PSCAD联合仿真实例,包括 hvdc_fourier、hyst_plot、phasor、three_dim_plot等(The Co-Simulation of MATLAB and PSCAD，including hvdc_fourier、hyst_plot、phasor、three_dim_plot.)
