초록/해제: 요약 :This paper presents the performance evaluation of channel estimation algorithm using zero-delay constant gain for W-CDMA forward link over multipath Rayleigh fading channels. By obtaining BER performance through computer simulations, the constant gain algorithm is compared with the existing WMSA algorithm. The channel structure, modulation and pilot patterns are applied to the ARIB (Association of Radio Industries and Business) and 3GPP (3rd Generation Partnership Project) ITU-R proposal for the IMT-2000. The BER performance of constant gain algorithm is similar to WMSA algorithm at wide range of Doppler frequencies except Doppler frequency 20Hz below. The constant gain algorithm has simple structure and no channel estimation delay so that it is concluded the more effective algorithm for TPC (Transmitter Power Control).
