Abstract

In regular multi-carrier CDMA (MC-CDMA) receiver, timing of starting point of desired signal must be found with small error in order to correctly demodulate information carried by different subcarriers. This requires complicated timing acquisition for each user in the receiver of uplink MC-CDMA system due to the randomness of delays. In this paper, we remove this requirement for uplink receiver by providing a method using partial sampling demodulation. The proposed partial sampling minimum mean square error (MMSE) receiver is shown to have stronger capability of both interference suppression and near-far resistance than that of a regular symbol receiver. The proposed receiver can be implemented adaptively by using least-mean-square (LMS) algorithm. A training sequence is required to achieve initial adaptation.
