| 摘 要： | CDMA技术已经在当前第三代通信（3G）标准中得到广泛采用,其中多用户检测技术能明显地改善CDMA通信性能,提高其系统容量。本文充分利用空时二维信息来增强CDMA系统的性能,提出一种基于Tank-Hopfield网络多用户检测算法：利用T-H网络快速计算LS的能力,来求解空时多用户检测问题。分析和仿真实验表明该算法的有效性,相比传统的子空间等方法,该方法具备更好的收敛速度和检测性能。

| Abstract: | CDMA（Code Division Multiple Access）is widely used in current 3G standard,in which the MUD can be used to improve communication performance and capacity of CDMA.The space-time 2D information is proposed to enhance the performance of CDMA system,and a multi-user detection algorithm based on Tank-Hopfield network is designed.Due to the fast computation for LS,the T-H network is used to solve the space-time MUD problem.The analytical and simulated experiment prove that the algorithm has favorable detection performance and convergence rate compared with the classic sub-space method. |
