设计了一个扩频 系统，具有扩频解扩的功能。系统中采用的是瑞利衰落的信道。仿真的结果很好，系统的误码率很小(Designed a spread-spectrum system with spread spectrum despreading function. System is used in the Rayleigh fading channel. Good simulation results, the system bit error rate of the small)

说明：  matlab编写的FFT变换和滤波的程序(this is matlab code for fft transfering and filtering.)

This program describe a stimulation which is in Part 1: No-Relay Transmitted power. In part 2 Relay Transmitted Power (Two-hop transmission) and in Part 3: Plot the graph Simple Relay , No Relay , Optimum Power level

k-means算法实现以及Iris数据集(Implementation of K-means algorithm and Iris data set)

The Kalman filter is an efficient recursive filter that estimates the state of a linear dynamic system from a series of noisy measurements. It is used in a wide range of engineering applications from radar to computer vision, and is an important topic in control theory and control systems engineering. Together with the linear-quadratic regulator (LQR), the Kalman filter solves the linear-quadratic-Gaussian control problem (LQG). The Kalman filter, the linear-quadratic regulator and the linear-quadratic-Gaussian controller are solutions to what probably are the most fundamental problems in control theory.
