说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)

用于安捷伦信号源。将波形下载到函数发生器上的MATLAB程序(Download the code to the signal generator machine.)

ofdm的matlab仿真程序，对学习ofdm技术的人员来说比较实用(ofdm matlab simulation program, to learn ofdm technology officer for more practical)

一个基于互信息的图像配准源代码，采用粒子群优化算法源代码，可直接使用。(A mutual information based image registration source code, using particle swarm optimization algorithm source code can be used directly.)

说明：  借助MATLAB实现高通数字滤波器的设计(Using MATLAB to achieve high-pass digital filter design)

802.15.4a 信道程序.为无线通信协议802.15.4a 建模.(802.15.4a Channel procedures. For wireless communication protocol 802.15.4a modeling.)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

极大似然法，估算已知结点的位置，求出误差(Maximum likelihood method to estimate the location of known nodes, find the error)
