Sum-Rate Maximization Based on Power Constraints for Cooperative AF Relay Networks
In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...
متن کاملReduced Energy Consumption in Multi-Hop MIMO-AF Relay Systems
Energy consumption is an important performance indicator for ensuring both the economical and environmental sustainability of the next generation communication networks. Co-operative communication is an effective way of improving the communication system performances. In the proposed system, the energy consumption is reduced by means of reducing the BER in MIMO-AF systems. The total transmissio...
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 کاملAmplify-and-Forward SIMO/MISO Distributed Relay Networks under Power Constraints
This paper presents an optimal solution for amplify-and-forward (AF) single-input multiple-output (SIMO) and multiple-input single-output (MISO) wireless distributed relay networks. The optimal solutions are determined based on minimum mean square error (MMSE) criterion for optimum nondiagonal and diagonal relay amplifying matrices under the transmit power constraints at the relays. The bit err...
متن کاملDistributed Multiuser Two-Way AF Relaying Systems under Jamming Environment
A distributed multiuser two-way amplify-and-forward (AF) wireless relay strategy consisting of 2M sources (or 2M destinations) and N relays all equipped with single antenna per communication node is studied in this paper. All sources act as both sources and destinations with a self-interference cancelation process at the 2M destinations. The main objective is to design the closed-form of minimu...
