Precoder and Decoder Design for SNR Maximization in Amplify-and-Forward (AF) MIMO Relay Systems
2011 IEEE Vehicular Technology Conference (VTC Fall), 2011We 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.

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 ...

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.

Static hybrid amplify and forward (AF) and decode and forward (DF) relaying for cooperative systems
Physical Communication, 2011Abstract 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.
