Performance analysis of joint relay selection and transmission schemes in multiple-antenna two-way relay systems
In this paper, we consider a two-way relay system with two multi-antenna sources and multiple single-antenna relays and study the performances for various transmission schemes with the assumption that perfect channel state information (CSI) is available at both the sources and the relays. Although a transmission scheme that combines source beamforming and relay selection (BF-RS) is known to imp...
متن کاملJoint Relay-and-Antenna Selection and Power Allocation for AF MIMO Two-way Relay Networks
In this paper, we present a joint relay-and-antenna selection and power allocation strategy for multiple-input multi-output (MIMO) amplify-and-forward (AF) two-way relay networks (TWRNs). In our approach, we select the best transmit and receive antennas at the two sources, a best relay and a best transmit and receive antenna at the selected relay based on maximizing the minimum of the end-to-en...
متن کاملZero-Forcing based Multiuser Two-Way AF Relay Network under Relay Power Constraint
A two-way amplify-and-forward (AF) wireless relay network consisting of 2M sources with only a single antenna per source and one relay with multiple N antennas is studied with a self-interference cancelation process at the 2M destinations in this paper. All sources act as both sources and destinations. The closed form of the relay amplifying matrix is optimized under the relay transmit power co...
متن کاملRelay Deployment for AF-MIMO Two-Way Relaying Networks with Antenna Selection
—In this paper the outage-optimal relay deployment problem for amplify-and-forward (AF) multi-input multi-output (MIMO) two-way relaying network with antenna selection is studied. By utilizing an approximation of the outage probability, the outage-optimal relay location is shown feasible. On this basis a relay deployment scheme is developed by providing the near-optimal relay position in an ap...
متن کاملDiversity Analysis of Relay Selection Schemes for Two-Way Wireless Relay Networks
One-way wireless relay networks have recently received a lot of attention due to their ability to provide spatial diversity in fadingwireless environment.Moreover, performing single-relay selection is a very attractive method due to its cost effective implementation and superior performance. However, one-way relay networks with the half-duplex signalling suffer from a spectral efficiency loss. ...
