一种全新的智能算法----萤火虫群算法。该算法主要用于求解函数.(A new algorithm---- fireflies swarm intelligence. The algorithm used to solve function.)

demonstrates the compressive sensing using a sparse signal in Time domain. The signal consists of a UWB (Ultra Wide Band) pulse in time domain. The signal is sparse in Time domain and therefore K random measurements are taken in Frequency domain.

这一文件对于学习神经网络、支持向量机（svr）的同仁们会有很大的帮助。(This document for learning neural networks, support vector machines (svr)colleagues will be very helpful.)

采用迭代最小二乘法，根据GPS星历中伪距、卫星位置速度等信息解算接收机位置。(GPS position calculation by Least Square method.)

实现了零速修正的卡尔曼滤波算法，可实现个人室内导航。为读数据格式(Zero speed correction Kalman filter algorithm can achieve personal indoor navigation. Read data format)

文件夹“AWGN”说明了系统误码率在均衡前后随SNR增加的变化。 （1）绘制误码率曲线。运行m文件：main_picture,调用主函数：ofdm_AWGN。 （2）绘制星座点图。运行m文件：snr_xinzuotu(Folder )

灰色pid控制算法的matlab仿真～～可以参考！希望能对大家有所帮助！ (Gray pid control algorithm matlab simulation ~ ~ can refer to! The hope that it can be helpful to everyone!)

首先声明此并非原创！（侵删！）但是这个资源非常非常难找。是我从外网找了很久down下来的。地球-火星发射机会搜索并做出著名的猪排图（porkchop图）。内有教程（英文），非常清楚。另外我也将星历文件de421.bin整合进去了。可以直接运行。(porkchop , DE421, Earth-Mars)

LMS自适应滤波器结构模型， matlab(LMS adaptive filter structure model)

This project simulates the operation of wireless digital communications using Q-PSK and 8PSK modulator. The project consists of four steps: transmitter design, channel propagation effect, receiver design and finally measuring system performance.
