channel estimation using awgn

说明：  大家好，我是建模的新手，希望大家相互交流共同提高。只是一个教程。很有用的哦。(Hello everyone, I am modeling the novice, I hope everyone together to improve mutual exchanges. Just a tutorial. Oh, very useful.)

说明：  1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图 (1. Using Matlab generated sine wave, rectangular wave, as well as the white noise signal, and display their respective time-domain waveform of Figure 2. FFT to transform, showing their frequency spectrum, including sampling rate, frequency, data length of 3-on-demand. Made of the three signals in root-mean-square maps, power maps, as well as the number of root-mean-square map 4. Fourier Transform IFFT with the restoration of signals, and displays the sinusoidal signal the resumption of time-domain waveform)

在一定区域内画圆，各个圆以相同的速度膨胀，直至填满该区域。(Draw circles and the circles can be full in the rectancle )

说明：  使用粒子群算法对无线传感器网络进行聚类（PSO）(Particle swarm optimization (PSO) is used to cluster wireless sensor networks)

matlab版的图像配准程序，计算图像的线性变换和输出图像的大小(matlab version of the image registration procedures, the calculation of the linear image transformation and the size of output image)

说明：  本程序用矩阵实现有限差分算法，本程序求解第一类边界条件下无源矩形金属槽电位分布，计算电磁学。(A simple code for finite difference method.)

高斯法求解方程，在matlab中建立，求解方程并显示运算时间结果，用于对高斯法有一个更直观的认识。(Gauss method for solving equations, established in matlab, solving equations and displays the computation time results for the Gaussian method has a more intuitive understanding.)

This code realize the MUSIC algorithm.

对16QAM调制解调技术，主要实现了16QAM的调制(16QAM modulation)
