Research of a Channel Estimation Using the Receiving Gain in Smart Antenna System

This paper presents a channel estimation for obtaining the beamforming gain or/and diversity gain of reverse link in smart antenna system. In this paper, we proposed a new method that provide a beamforming gain or/and diversity gain on a real-time basis arbitrarily according to angle spread produced at every snapshot. From the result of performance analysis through various simulation in CDMA2000, it is confirmed that proposed method is far superior about 3-4 times compare to single antenna in signal environment of wide angle spread.
