초록/해제: 요약 :This paper presents an application method of auxiliary pilot channel and receiving performance of downlink beamforming smart antenna system at mobile terminal in CDMA mobile communication system. Downlink beamforming maximizes the gain by transmitting the signal to the direction of desired user and minimizes the interference by nulling the direction of undesired users. The auxiliary pilot is used to provide an exact channel estimation to each mobile terminal in downlink beamforming. In this paper, we analyze the performance of fundamental channel and supplemental channel in downlink beamforming smart antenna system and compare the performance of downlink beamforming of smart antenna system using the auxiliary pilot channel to that of one antenna system under CDMA2000 1X signal environment.
