Abstract

In this paper, we consider the uplink of SC-based (single-carrier) block transmission systems where the transmission bandwidth associated to each channel, exceeds the symbol rate and we can have significant overlapping between adjacent channels. We present an iterative frequency-domain receiver for joint equalization and ACI (adjacent channel interference) suppression taking advantage of spectral correlations for the separation of cyclostationary signals. Our performance results show that the BER (bit error rate) performances with strong ACI levels can be similar to the ones without ACI. Moreover, after a few iterations these performances can be close to MFB (matched filter bound)
