Achievable data rates and power allocation for frequency-selective fading relay channels with imperfect channel estimation
(Springer Science+Business Media, 2012-12)In this article, we investigate the information-theoretical performance of a cooperative orthogonal frequency division multiplexing (OFDM) system with imperfect channel estimation. Assuming the deployment of training-aided ... -
High-rate distributed space-time-frequency coding for wireless cooperative networks
(IEEE, 2011-02)In this paper, we propose high-rate distributed space-time-frequency codes (DSTFCs) to exploit maximum achievable diversity gains over frequency-selective fading channels. The proposed designs achieve full-rate for any ... -
Novel distributed space-time trellis codes for relay systems over cascaded rayleigh fading
(IEEE, 2010-12)In this letter, we consider the deployment of distributed space-time trellis codes (STTCs) for user cooperation. We derive a pairwise error probability (PEP) expression for distributed STTCs over cascaded Rayleigh fading ... -
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 ... -
Performance analysis of cooperative diversity networks with imperfect channel estimation
(IEEE, 2010)In this paper, we investigate the effect of channel estimation error on the error rate performance of a multi-relay system with amplify-and-forward relaying. We consider orthogonal relaying and study both conventional ...
