Code

直接序列扩频通信中采用QPSK调制时，须将产生的串行数据首先串并变换成两路，本程序就是实现这种串并变换！(Direct sequence spread spectrum communications using QPSK modulation, it is necessary to have a string of serial data and converted into the first two, the process is to realize such a string, and transform!)

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)
