Optimal bit and power loading for amplify-and-forward cooperative OFDM systems
(IEEE, 2011-03)
In this paper, we investigate bit and power allocation strategies for an orthogonal frequency division multiplexing (OFDM) cooperative network over frequency-selective fading channels. We assume amplify-and-forward relaying ...
On the performance analysis of multirelay cooperative diversity systems with channel estimation errors
(IEEE, 2011-06)
In this paper, we investigate the performance of an amplify-and-forward (AF) cooperative diversity system with multiple relays in the presence of channel estimation errors. We consider both conventional relaying (in which ...
