| 摘 要： | 提出了一种行之有效的将智能天线技术同多用户检测技术结合的空-时接收方法,并对其参数进行了优化。它根据误码率信息有选择地实施干扰消除,先并行消除低误码率用户信号的影响,再检测高误码率用户信号。它复杂度低,计算效率高,易于实时实现,具有很好的应用价值。蒙特卡洛仿真实验表明,该方法可以显著改善码分多址移动通信系统的性能。

| Abstract: | An effective space-time receiver scheme that combines smart antennas with multiuser detection is proposed and its parameter is optimized. It detects signals for users with high BER after canceling detected signals for users with low BER in parallel. Its low complexity and high computation efficiency make it very suitable for real-time application. Monte Carlo simulations in a CDMA mobile telecommunication system verified its effectiveness in improving system performance. |
