Robust equalisation for inter symbol interference communication channels
IET Signal Processing, 2012 The problem of equalisation for communication channels with inter symbol interference (ISI) is investigated in this study. One practical yet challenging constraint for a channel with high transmission rate is incorporated into the modelling of the equalisation system: the communication channel is subject to uncertainties, which are assumed to be within

An inter user interference cancellation scheme for two users in full-duplex MIMO system
EURASIP Journal on Wireless Communications and Networking, 2018 The inter-user interference is a critical performance degradation factor in a full-duplex multi-user system. However, the conventional pre-processing filters, such as null space projection filter and regularized channel inversion filter, are unsuitable ...

Inter-Numerology Interference for Beyond 5G
IEEE Access, 2019 Fifth generation (5G) radio access technology (RAT) is designed to flexibly serve multiple services with extremely diverse requirements. One of the steps taken toward fulfilling this vision of 5G-RAT is the introduction of multi-numerology concept, where

Journal of Physics: Conference Series, 2021 Abstract Proposals for improving the noise immunity of receiving phase-shift keying signals in the conditions of inter-symbol interference caused by fading in the channel are presented. The use of Barker sequences for the expansion of modulating information pulses has been substantiated.

An identification technique for the co-frequency mixed communication signals based on cumulants
EURASIP Journal on Advances in Signal Processing, 2018 Identification of the co-frequency interference is a common problem in wireless digital communication systems. The high-order statistics (HOS) feature based on cumulants is a widely adopted solution. However, prior knowledge of the timings and the symbol
