| 摘 要： | 直接序列码分多址分组多用户检测中,干扰用户包括小区分组外用户及相邻小区用户.首先利用子空间投影方法,在所有干扰用户中识别出相邻小区用户,然后对小区内用户进行多用户检测,并通过子空间跟踪方法实现自适应.既保证了性能,又降低了计算复杂度.仿真结果表明算法是实用的.

| Abstract: | For group multiuser detection of DS-CDMA,the whole interferers were composed of the users in local cell and those in neighbor cells.Firstly,users in neighbor cells were identified from the received interferers by using subspace projection.Then,multiuser detection was performed among the users in local cell.The adaptive algorithm was achieved by subspace tracking.Through this processing,the complexity of calculation is decreased and the performance is improved.Simulations demonstrate that the algorithm is applicable. |
