The received signal is correlated when applying the beamforming algorithm in the smart antennas system.Two main factors determine the un-correlation of the channel: the distance of antenna and the angular spread.In the paper a vector channel simulation model are presented based on geometrical environment and statistical data, then the vector channel correlation is analyzed.Subsequently, the beamforming algorithm which maximums the received desired power is adopted to analyze the effects of different angular spread on the downlink performance in TD-SCDMA system with smart antennas.Final the simulation result is presented.
