Achievable Rates for Multiuser Interference Relay Channel
2010 IEEE International Conference on Communications, 2010We consider the interference relay channel (IRC) where a single relay assists the communications between multiple source-destination links under the half-duplex (HD) constraint. We assume each source has an independent message and its transmitted signal may cause interference at the other destinations.

Optimal Transmission in MIMO Channels With Multiuser Interference
IEEE Transactions on Wireless Communications, 2018Cochannel interference is one of the inevitable deleterious components in designing and analyzing of a wireless network. The use of multiple antennas at both transmitting and receiving nodes is a promising technique to suppress and/or alleviate the effect of cochannel interference on capacity.

IEEE Transactions on Wireless Communications, 2007
We propose a two-stage precoder/equalizer to suppress intercarrier interference (ICI) and multiuser interference (MUI) in downlink multiuser OFDM with multiple transmit antennas. The first stage, non-linear Tomlinson-Harashima preceding (THP) at the base station (BS) transmitter, mitigates the effect of the spatial inter-stream interference caused by ...

Opportunistic Interference Aligned User Selection in Multiuser MIMO Interference Channels
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010In this paper, we propose a practical interference alignment technique based on an opportunistic user selection in a three-user $2\times 2$ MIMO interference channel where no information is allowed to be shared among transmitters. In the proposed scheme, the user whose interference signals from other transmitters are most aligned with each other is ...

Adaptive interference suppression in multiuser OFDM
IEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005Orthogonal frequency-division multiplexing (OFDM) with multiple access has been proposed for future wireless networks because of its resistance to channel multipath effects and narrowband interference. In a multiuser OFDM (MU-OFDM) network employing frequency-division multiple-access (FDMA), users of a base station operate on different subcarriers.

Interference cancellation for multirate multiuser systems
IEEE VTS 53rd Vehicular Technology Conference, Spring 2001. Proceedings (Cat. No.01CH37202), 2002Multistage successive interference cancellation (SIC) and multistage parallel interference cancellation (PIC) are compared under two different realistic dual rate asynchronous DS-CDMA schemes. The effect of power control and imperfect channel side information are also considered.

Cooperative interference cancellation for multiuser transmission
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007This paper proposes a novel interference cancellation scheme that utilizes relay stations in multi-user transmission systems. Unlike conventional relay transmission schemes, the relay stations are used to decode the interference and transfer the pertinent information to the mobile stations.

Parallel interference cancellation in multiuser detection
Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002The parallel interference cancellation (PIC) principle is a conceptually simple and yet effective method of parameter estimation and data detection in the presence of multiple-access and multipath interference. It unifies some of the known methods of data detection, complex channel coefficient estimation, as well as delay tracking in DS-CDMA receivers.

A comparison of interference cancellation and multiuser detection
Proceedings. Asia-Pacific Conference on Environmental Electromagnetics. CEEM'2000 (IEEE Cat. No.00EX402), 2002We investigate the use of an antenna array at the receiver in FDMA/TDMA systems, to let several users share one communication channel within a cell. A decision feedback equalizer which simultaneously detects all incoming signals (multiuser detection) is compared to a set of decision feedback equalizers, each detecting one signal and rejecting the ...
