A new pilot-aided channel estimation technique is proposed and applied to wideband CDMA (WCDMA) systems. This technique is based on conventional pilot-aided decision directed (PADD) algorithms. In this letter, conventional PADD algorithms are studied extensively and a modified PADD algorithm is presented. The performance of the proposed algorithm is compared with that of conventional PADD algorithms through computer simulations in Rayleigh fading environments.
