Description: 针对多输入多输出空间相关信道环境,提出了一种基于格规约理论的最小均方误差检测算法.该算法考虑了空间相关性的影响,利用复数Lenstra-Lenstra-Lovász格规约算法克服了传统的线性最小均方误差检测器分集阶数随相关系数增加而减小的缺点,使检测到的信号在高信噪比下可以达到比传统算法低个数量级的误码率.理论分析与仿真结果表明,在信道为Kronecker相关平坦衰落模型下,接收端采用最小均方误差信道估计,发射端采用QPSK调制未使用信道编码,当比特信噪比大于18dB时,基于格规约理论的最小均方误差检测器的误码率低于传统最小均方误差检测器的误码率 发射端采用(2,1,3)卷积码、接收端采用硬判决Viterbi译码,当信噪比大于16dB时,基于格规约理论的最小均方误差检测器的误码率低于传统最小均方误差检测器的误码率,且基于格规约理论的最小均方误差检测器的分集阶数不受相关系数的影响,等于接收天线数N.-Toovercomethedrawbackthatthediversityorderofthetraditionallinear MMSEdetection

Description: 1. 程序中Turbo译码采用了MAP,LOG-MAP，和MAX-LOG-MAP三种算法。
2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数，保存下来的目的是
加快仿真的速度，如果你所仿真的Turbo码不是程序中列出的任意一种，你可以通过函数
trellis来生成自己的相关参数。
3. 程序支持1/2和1/3两种码率的Turbo码，其中1/2码率的Turbo码通过矩阵[1 0 0 1]打
孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。
4. 程序中的信噪比表示Eb/N0，通过此参数求得N0，对发送信号进行加噪。-1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.
