Asynchronous and Non-Stationary Interference Cancellation in Multiuser Interference Channels
IEEE Transactions on Wireless Communications, 2021A single antenna interference cancellation (SAIC) scheme is proposed. The scheme is motivated by the challenging asynchronous and non-stationary interference cancellation problem in wireless communications. Suppose the existence of the single-user region (SUR) of the desired signal, we propose to first recognize the SUR via a novel detection scheme ...

Interference Forwarding in Multiuser Networks
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008We study communication in networks with multiple source-destination pairs and relays. In such networks, the channel output at any destination receiver consists of both the desired signal and interference. In this setting the relay can help forward the desired message of a user to the destination receiver, or help forward interference to a receiver to ...

Clustering for Interference Alignment in a Multiuser Interference Channel
2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012Interference alignment (IA) has been shown as a promising technique to achieve the optimal capacity scaling of a multiuser interference channel at asymptotically high signal-to-noise-ratio (SNR). However, in practical communication systems, mitigating all interference via IA is not necessary since some of them only have negligible effect due to path ...

Interference suppression for uplink multiuser CDMA
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004Techniques are proposed for interference suppression for the uplink of multiuser CDMA systems. The multiuser CDMA uplink communication system model is described in space-time domain form through an antenna array and a multipath expression. A linear prediction technique is used to perform channel estimation.

Soft interference cancellation in multiuser communications
Wireless Personal Communications, 1996In this paper the performance of soft interference cancellation in synchronous multiuser channels is investigated. Two-stage detection with decorrelator in the first stage is considered. Soft first stage tentative decisions are formed by means of a multilevel quantizer or linear clipper.

Turbo multiuser detection with unknown interferers
IEEE Transactions on Communications, 2002We consider the problem of turbo multiuser detection over synchronous CDMA channels in the presence of interfering users whose signature sequences are unknown. We will see that the new receiver significantly outperforms the conventional turbo multiuser receiver in the presence of unknown interferers, even in situations in which the conventional turbo ...

Blind multiuser detection via interference identification
IEEE Transactions on Communications, 2002Previous results on blind multiuser detection apply in situations where the signal parameters of the users of interest are known, and those of the interferers; are unknown. In this paper, we consider the new paradigm of an N-user system, in which K users are active, and the problem is to detect G users of interest out of those K active users when the ...

Iterative multiuser interference reduction: turbo CDMA
IEEE Transactions on Communications, 1999Summary: We view the asynchronous random code-division multiple-access (CDMA) channel as a time-varying convolutional code. We study the case where the users encode their data, and, therefore, the single user transmitters and the CDMA channel appear as the concatenation of two coding systems.

A Review on Interference Alignment in Multiuser Interference Channels
Wireless Personal Communications, 2015As the density of base stations in wireless networks becomes higher, system performance is limited not by noise but by interference from other transmitters and so research on interference channels has been actively undertaken. In this article, we study interference alignment (IA) techniques, which are known to maximize the achievable degrees of freedom
