摘　　要：该文提出了一种基于对波束和信道进行同时搜索的转换波束智能天线方案,并进一步分析了采用该方案时系统上行链路的信干比(SIR)性能。该方案较之传统的波束和信道分别搜索和选择的各自方案有一定的优越性,符合未来移动通信系统中智能天线的发展方向。This paper proposes a switched-beam smart antennas scheme which is based on the simultaneous searching of beams and channels, and analyzes the SIR performance of uplink in system when applying the scheme. The proposed scheme has better performance compared with the traditional respective searching scheme of singular searching of the beams and channels. It accords with the developing way of smart antennas in future mobile communication systems.
