Abstract

We consider the problem of joint equalization and narrowband interference (NBI) suppression in orthogonal frequency-division multiplexing (OFDM) systems. Since the conventional zero-forcing (ZF) receiver does not assure satisfactory interference suppression capabilities in severe interference environments, we investigate the potential of the minimum mean-square-error (MMSE) receiver, evaluating in particular the advantage that can be achieved by exploiting the redundancy contained in the cyclic prefix of the OFDM signal.
