摘　　要：研究了运用迭代最小二乘 (RLS)算法的智能天线系统提高IS 95系统抗多址干扰性能的方法 .通过正交的本振信号实现了接收信号的复信号提取 ,运用RLS解扩频重扩频多目标阵列 (DRMTA)的方法 ,结合IS 95系统本身所具有的分集接收的特点 ,成功实现了IS 95系统的多径。This paper focuses on the effect of a RLS algorithm smart antenna employed in IS 95 system. With orthonormal local oscillation signals, a complex signal was retrieved. The multi path and multi space signals in IS 95 system were received by the use of de spread re spread multi target array method and RAKE receiver. The simulation showed that it was a good way to suppress noise signals in the system.
