A two-way relay-interference channel describes a system of four communicating transceivers with two interjacent parallel relays arranged in a bidirectional 2 × 2 × 2 relayinterference network. Two pairs of transceivers are each communicating bidirectionally with the aid of both relays. All transceivers and relays are assumed to operate in full-duplex mode. Since Interference Neutralization is k...

Abstract—Previous studies on analog network-coded two-way relay (ANC-TWR) assumed the same modulation and coding both for the mobile terminal (MT)-relay station (RS) link and the base station (BS)-RS link. In this paper, we propose an adaptive ANC-TWR, where adaptive modulation and coding (AMC) is employed in order to maximize the uplink (MT-RS-BS) and downlink (BS-RS-MT) throughputs. The singl...

This paper investigates the capacity of a wireless two-way relay channel in which two end nodes exchange information via a relay node. The capacity is defined in the information-theoretic sense as the maximum information exchange rate between the two end nodes. We give an upper bound of the capacity by applying the cut-set theorem. We prove that this upper bound can be approached in low SNR reg...

Although underlay networks mitigate the dual problems of spectrum congestion and spectrum under-utilization, the bi-directional (primary-to-secondary and secondaryto-primary) interference issues must be addressed to improve their reliability, coverage and capacity. To address these problems, this thesis investigates beamforming and two-way relaying. Specifically, the two underlay configurations...
