波束赋形技术是智能天线在TD-SCDMA系统中的主要应用之一,简要介绍了智能天线波束赋形的原理,并对比了天津地区无线设备厂家和天线厂家的权值设置的波束赋形的仿真效果。在天津TD-SCDMA系统的网络优化中,根据地域信号覆盖特点,通过修改天线权值参数、优化广播信道波速赋形效果达到了改善TD网络信号覆盖的目地。
Beamforming technology is one of the main applications of smart antenna in TD-SCDMA system. The principle of smart antenna beamforming is introduced briefly. The beamforming of wireless device manufacturers and antenna manufacturers in Tianjin is compared Simulation effect. In the network optimization of TD-SCDMA system in Tianjin, according to the characteristics of geographical signal coverage, it is achieved that the signal coverage of TD network can be improved by modifying the antenna weight parameters and optimizing the wave shaping effect of the broadcast channel.
