In this paper, a decorrelator for multiuser detection derived from ML criteria in CDMA system is proposed for frequency selective fading channels. Simulations prove the better performance of this method than the method proposed by Zvonar in which the paths of the same user are combined after decorrelating. This method utilizes equivalent spreading codes for decorrelating, thus the hardware complexity is reduced.
