实现电力线通信信道建模及其基于OFDM调制系统环境下仿真。(Power line communication channel modeling and simulation of OFDM system)

将shp格式的GIS数据转为ENVI EVF格式(GIS data shp format to format ENVI EVF)

蚁群算法+Dijkstra算法=二维路径规划(Ant colony algorithm+Dijkstra algorithm-two-dimensional path planning)

说明：  EMD分解算法 工具箱 对数据进行EMD分解(EMD decomposition algorithm)

本程序是用于三维图像的，三维重建，非常有用(This procedure is used for three-dimensional images, three-dimensional reconstruction, a very useful)

说明：  无线衰落信道下的通信仿真，可以更换几种常见的衰落模型，如莱斯衰落，瑞利衰落等(Several common fading models, such as rice fading and Rayleigh fading, can be replaced in the communication simulation of wireless fading channel.)

该程序基于MATLAB平台编写，实现了GPS/INS基于位置松组合的卡拉曼滤波算法，分为两部分，GPS_INS.m为组合算法主文件，输入捷联惯导平台实测数据，设置各量测噪声参数，在调用卡尔曼滤波函数进行数据融合校正，最后实现绘图功能；kalman_GPS_INS.m 为卡拉曼滤波程序，输入量测误差以及各噪声参数可得位置和速度估计值。(The program is based on MATLAB platform, and realizes the Kalman filtering algorithm of GPS/INS based on position loosening combination. It is divided into two parts. GPS_INS.m is the main file of the combined algorithm, inputs the measured data of the strapdown inertial navigation platform, sets the measurement noise parameters, and carries out data fusion correction by calling the Kalman filter function, and finally realizes the drawing. Function; kalman_GPS_INS.m is Kalman filter program, input measurement error and noise parameters can be estimated position and velocity.)

说明：  使用ncread循环读入所需要的nc数据，大致就是这么一个工具(Using ncread loops to read the required NC data is roughly such a too)

说明：  粒子群优化算法工具箱，包含完整的参数优化子程序(Particle swarm optimization algorithm toolbox, including a complete parameter optimization subroutine)

本程序是写的是扩展高斯（EGF）滤波器，当两个输入为根号1/2的时候就是IOTA滤波器，用于通信系统发端的波形塑形(This function calculates a filter with egf characteristic)
