协作OFDM简单实现，采用AF模式，分析其性能(This file is simply realizing cooperative OFDM communicaiton about AF mode)

维纳滤波器有以下三种用途：过滤，平滑，预测，其计算可以归结为求解维纳霍夫方程(filter)

function [a,b] = pade(x,p,q) PADE Model a signal using the Pade approximation method ---- Usage: [a,b] = pade(x,p,q) The input sequence x is modeled as the unit sample response of a filter having a system function of the form H(z) = B(z)/A(z) The polynomials B(z) and A(z) are formed from the vectors b=[b(0), b(1), ... b(q)] a=[1 , a(1), ... a(p)] The input q defines the number of zeros in the model and p defines the number of poles.

MATLAB code demonstrating digital MSK

一个简单的OFDM程序，有IFFT/FFT，QPSK调制解调，加入了高斯噪声，加入循环前缀。并且每行程序都有的详细注释，简单易懂。扩展性比较强，可以改写成自己的代码。(A simple OFDM procedures, there are IFFT/FFT, QPSK modulation and demodulation, joined the Gauss noise, adding a cyclic prefix. And each line of the program are detailed notes, easy to understand. Expansion is relatively strong, can be rewritten into their own code.)

说明：  超声声场的线性描述与仿真工具，可以作为超声系统的研究有用工具，根据不同的输入 ，得到不同的超声图像，验证自己的算法。(ultrasound field simulation code)
