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 ...
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 ...
