| 摘 要： | 该文提出了一种基于天线阵列的预处理判决反馈最小二乘恒模盲多用户检测算法，称为P-DFB-LSCMA算法。它是对天线阵列接收信号经预处理，采用判决反馈最小二乘恒模算法进行多用户检测。仿真结果表明，P-DFB-LSCMA算法比仅采用判决反馈最小二乘恒模算法(DFB-LSCMA)和传统的LSCMA算法性能要好，特别在低信噪比下性能仍优于后二者。

| Abstract: | A Pre-processing Decision-FeedBack Least Squares Constant Modulus blind multiuser detection Algorithm (P-DFB-LSCMA) using antenna arrays is proposed in this paper. It pre-processes the received signals from the antenna arrays and utilizes the least squares constant modulus algorithm based on decision feedback to detection the DS-CDMA signals. Simulation results show that the proposed P-DFB-LSCMA algorithm is superior to DFB-LSCMA and LSCMA, especially with low SNR. |
