Precoder and Decoder Design for SNR Maximization in Amplify-and-Forward (AF) MIMO Relay Systems

2011 IEEE Vehicular Technology Conference (VTC Fall), 2011
We address the problem of designing linear precoder and decoder for single symbol transmission in three node amplify-and-forward (AF) multi-input-multi- output (MIMO) relay systems where all the nodes are equipped with multiple antennas and the source and the relay nodes are subject to individual transmit power constraints.

Relay and antenna selection in multi-antenna amplify-and-forward (AF) systems with partial channel state information

2012 IEEE International Conference on Communications (ICC), 2012
This paper combines the idea of relay and antenna selection with that of partial channel state information (CSI) based precoding. We consider a non-regenerative two-hop relay network where all the nodes are equipped with multiple antennas. It is assumed that multiple relay nodes are available for cooperation and that the source and each individual ...

Static hybrid amplify and forward (AF) and decode and forward (DF) relaying for cooperative systems

Physical Communication, 2011
Abstract In this paper, we propose a static hybrid amplify and forward (AF) and decode and forward (DF) relaying protocol for cooperative systems. In such a scheme, relays close to the source amplify the received signal whereas the remaining relays transmit only if they decode correctly.

Performance Analysis of Code Combining Based Cooperative Protocol with Amplified-and-Forward (AF) Relaying

IEICE Transactions on Communications, 2010
In this letter, we analyze the error performance of a code combining based cooperative diversity protocol. For coded transmission schemes, code-combining can obtain a near optimal low rate code by combining repeated codewords. An analytical method for evaluating the performances of such scheme is presented.
