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.

Space-Time Codes for Amplify-and-Forward (AF) Relay Channels: Performance and Code Design

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
We consider the analysis and design of space-time trellis codes (STTCs) for a cooperative relay channel operating in amplify-and- forward (AF) mode assuming the source and destination nodes are equipped with multiple antennas but the relay node has single antenna.

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.

Precoder design and node power allocation in multi-antenna amplify-and-forward (AF) relay systems

2013 IEEE International Conference on Communications (ICC), 2013
In this paper, the problem of precoder design and node power allocation in a three node cooperative multiple-input multiple-output (MIMO) relay system is discussed. All the nodes are assumed to be equipped with multiple antennas and the source and the relay nodes are subject to a total transmit power constraint. We first introduce an upper bound on the

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 ...
