Optimal Channel Pairing and Power Allocation for Multi-channel Multi-hop Relay Networks
We study the problem of channel pairing and power allocation in a multi-channel, multi-hop relay network to enhance the end-to-end data rate. OFDM-based relays are used as an illustrative example, and the amplify-andforward and decode-and-forward relaying strategies are considered. Given fixed power allocation to the OFDM subcarriers, we observe that a sorted-SNR subcarrier pairing strategy is ...
متن کاملEM-based Semi-blind Channel Estimation in AF Two-Way Relay Networks
We propose an expectation maximization (EM)based algorithm for semi-blind channel estimation of reciprocal channels in amplify-and-forward (AF) two-way relay networks (TWRNs). By incorporating both data samples and pilots into the estimation, the proposed algorithm provides substantially higher accuracy than the conventional training-based approach. Furthermore, the proposed algorithm has a lin...
متن کاملBounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel
In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
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 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...
