802.3af/at标准,POE 供电协议(standard of 802.3af/at)

说明：  ofdm的编码过程，用evm和比特率进行对比(The encoding process of OFDM is compared with EVM and bit rate)

简单的MIMO模拟 假定QPSK，ML解码（SM ZF检测器除外）。 mrc.m - 最大比例组合 stc.m - 具有1和2个接收天线的Alamouti空时分组码 bf.m - 特征波束形成 sm.m - 空间复用2x2（ML解码和次优逼迫） 简单的OFDM仿真 模拟保护带，用于信道估计的循环前缀前导码符号(Simple MIMO simulations Assumes QPSK, ML decoding (except SM ZF detector). mrc.m - maximal ratio combining stc.m - Alamouti space-time block code with 1 and 2 receive antennas bf.m - Eigen-beamforming sm.m - Spatial multiplexing 2x2 (both ML decoding and suboptimal zero forcing) Simple OFDM simulation Simulates guard band, cylic prefix Preamble symbol used for channel estimation)

用Matlab写的关于UDP（用户数据报协议）下的主机间的数据通讯。如需运行这个程序，只需把程序中的IP替换成你的主机IP地址即可(Written in Matlab data communication between host UDP (User Datagram Protocol). To run this program, simply replace the IP program into your host IP address can be)

这是一篇讲通信理论的文章，非常经典，可以作为课外学习使用 (This is an article tackling with communication theory, very classic, can be used as extra-curricular learning)

百度手机地图 实例集合，应用程序编程源码，很好的参考资料。(Set Baidu mobile phone map example, application programming source code, a good reference.)

说明：  OFDM计算，调制方式为64QAM，可以对信道的信息进行估计(OFDM calculation, modulation mode is 64QAM, can estimate the channel information)
