Abstract

IMT-DS system is one of the approved 3G radio interface standard which employ Rake receiver to exploit multipath diversity. This paper discusses a new dimension in DS-CDMA channel estimation i.e., chip-level adaptive channel estimation. A novel despreader-respreader based channel estimator (DRCE) is proposed to obtain uplink (UL) channel estimates at chip-level which resolves the deficiencies of conventional methods that work at symbol level. The DRCE employs adaptive filter whose weights are adapted by using LMS algorithm. The performance of Rake receiver with DRCE for IMT-DS system is evaluated in terms of BER by simulations for pedestrian and vehicular channels.
