摘要
智能天线技术将信号处理由空域、时域、码域扩展到了空域，它已成为第3代移动通信系统的关键技术之一。本文结合IS－95和cdma2000系统的特点，仿真并分析智能天线对CDMA系统上行链路性能的影响。
Smart antenna has become one of the key technologies in the third generation mobile communications systems, due to its ability of separating different users by spatial information In this paper, we apply it to IS 95 and cdma2000 systems uplink, simulate the above two systems and analyze antenna array's performance
