Distributed Relay Beamforming in Cognitive Two-Way Networks: SINR Balancing Approach
In this paper, we study the problem of distributed relay beamforming for a bidirectional cognitive relay network which consists of two secondary transceivers and K ognitive relay nodes and a primary network with a transmitter and receiver, using underlay model. For effective use of spectrum, we propose a Multiple Access Broadcasting (MABC) two-way relaying scheme for cognitive networks. The two...
متن کاملOn Design of Distributed Beamforming for Two-Way Relay Networks
We consider a two-way relay network, where two source nodes, S1 and S2, exchange information through a cluster of relay nodes. The relay nodes receive the sum signal from S1 and S2 in the first time slot. In the second time slot, each relay node multiplies its received signal by a complex coefficient and retransmits the signal to the two source nodes, which leads to a distributed two-way beamfo...
متن کاملBeamforming for Underlay Two - Way Relay Networks
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...
متن کاملPower Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
متن کاملOptimal Beamforming in Two-Way Relay Networks with Cognitive Radio Capabilities
In this paper, we present a cognitive relay network with two primary transceivers that communicate via several distributed relay terminals. Spectrum sensing is deployed at the relays to sense the absence/presence of the primary transceivers based on energy detection. The primary network utilizes a two-step two-way amplify-and-forward (AF) scheme by using the cognitive radio (CR) terminals as it...
