Dual Hop Relay with Cooperative Diversity and Relay Selection
As wireless communication becomes more prevalent, the demand for higher data rates and uninterrupted connectivity is increasing. Future wireless systems are provisioned to be highly heterogeneous and interconnected. On one side, wireless ad hoc networks are emerging for a wide range of new applications, on the other side; infrastructure based broadband wireless systems are expanding to provide ...
متن کاملJoint source and relay design for two-hop amplify-and-forward relay networks with QoS constraints
In this paper, we consider the joint design of source precoding matrix and the relay precoding matrix in a two-hop multiple-input multiple-output relay network. The goal is to find a pair of matrices in order to minimize the power consumption and at the same time meet pre-selected quality of service constraints that are defined as the mean square error of each data stream. Using majorization th...
متن کاملLow-Complexity QL-QR Decomposition Based Beamforming Design for Two-Way MIMO Relay Networks
In this paper, we investigate the optimization problem of joint source and relay beamforming matrices for a twoway amplify-and-forward (AF) multi-input multi-output (MIMO) relay system. The system consisting of two source nodes and two relay nodes is considered and the linear minimum meansquare-error (MMSE) is employed at both receivers. We assume individual relay power constraints and study an...
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...
