| Abstract: | In TD-SCDMA system the most important character is of the smart antenna technology,whose core is the downlink beamforming in the smart antenna technology.The effect of disturb ance and noise was synthetically put into consideration.The ideal beamforming algorithm and its implementation method were all simulated in different channel environments based on MMSE criteria and performance was simulated as far as the algorithm was concerned.Conclusions were analyzed and the system performance was improved. |
