| 摘 要： | 提出一种利用天线阵列的多用户检测方法.新方法假设各个信号源的训练序列互相正交,并且各信号源都是幅度为1的恒模信号.结合无空间模糊性的T型阵列,新方法能快速、精确地估计波达方向矩阵,进而检测多个用户的信息,利用Matlab对算法进行了仿真实验,并给出了新方法的误码率性能.

| Abstract: | A new method of multi-user detection by using antenna array is presented. The training signals of users are mutualy orthogonal and the magnitude of each signal is 1. Combined with T shape antenna array,the new algorithm can estimate the DOA matrix accurately and rapidly,and detect the information of Multi-Users. Finally,the computer experiment is done with Matlab,and the result shows the performance of error bit of the new method. |
