| Abstract: | The beamforming technology is the main application of smart antenna in TD-SCDMAsystem. This article describes the smart antenna beamforming principle. And the comparisons are made on the simulation results of antenna beamforming with different weight parameters provided by radio equipment manufacturer and antenna equipment manufacturer. According to the characteristics of local signal coverage, the coverage of TD network is improved by revising weight parameter of antenna beamforming and optimizing antenna beamforming effect of broadcast channel in Tianjin TD-SCDMA optimization. |
