OFDM

this code is to select the coefficients

pd estable for ball and beam

说明：  空时码的编码程序，包含不同码字的比较和多天线设计(STBC source code with MIMO)

surf算法，实现特征点检测和匹配.文件内有两个图像匹配实例(surf algorithm, feature point detection and matching)

关于OFDM多智能体下的功率分配，并与注水法做了比较(OFDM on multi-agent of power allocation, and with the water injection method were compared )

人工神经网络在Matlab上的仿真作业，自己亲自仿真出来的，希望大家下载！(Artificial Neural Network in Matlab simulation on the job, personally simulation out, hope everyone to download!)

非常好QPSKQAM256matlab代码！(QPSKQAM256matlab)

快速傅里叶变换过程描述，matlab运行环境中实现(Fast Fourier Transform process description, matlab environment to achieve)

射频电路设计，微波设计中常常用到的smith原图，本程序利用MATLAB编程画出smith原图，可以帮助射频电路设计，比如画等功率匹配圆，等阻抗圆，等反射系数圆等。(RF circuit design, microwave design is often used smith artwork, this program using MATLAB to draw smith original programming that can help RF circuit design, such as painting and other power matching round, such as impedance circle, so the reflection coefficient circle and so on.)
