DOI: 10.1109/access.2018.2871731
Abstract: This paper develops a new spatial model for non-orthogonal multiple access (NOMA)-based two tier-cellular network underlying inband device-to-device (D2D) communication with randomly deployed base stations and users. In particular, we model the locations of users… read more here.

DOI: 10.1109/tvt.2022.3185266
Abstract: In this paper, we consider a multi-user interference network where a central controller allocates power resources to multiple base stations for maximizing the entire network utility under a long-term power budget constraint. The optimal power… read more here.

DOI: 10.1186/s13638-018-1186-2
Abstract: 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 for user pre-processing… read more here.

DOI: 10.3390/e21111092
Abstract: In this paper, the K-user interference channel with secrecy constraints is considered with delayed channel state information at transmitters (CSIT). We propose a novel secure retrospective interference alignment scheme in which the transmitters carefully mix… read more here.

DOI: 10.3390/e24081078
Abstract: In this paper, we study the degrees of freedom (DoF) of a frequency-selective K-user interference channel in the presence of an instantaneous relay (IR) with multiple receiving and transmitting antennas. We investigate two scenarios based… read more here.
