Abstract

This paper evaluates the performance of widely linear filtering based equalization for suppression of kindred co-channel interference. The presented approach is extension of the MMSE method proposed for ICI/ISI compensation for OQAM/FBMC transmission system in [1][2]. The analysis and computer simulation results show the relevance of widely linear filtering based equalization approach when the interfering signal exhibit improper statistics. This indicates the need to consider alternative forms of I/Q staggered multicarrier waveforms for 5G standardization that differs from the conventional one with 100% roll-off subchannels.
