Cooperative communications in conjunction with orthogonal frequency division multiplexing (OFDM) has recently emerged as a promising technique to mitigate multi-path fading and provides high spectral efficiency in broadband wireless communications systems. In this paper, we investigate resource allocation of an OFDM modulation scheme combined with distributed space-frequency codes (DSFC) based upon...
Cooperative communication in conjunction with orthogonal frequency division multiplexing (OFDM) has recently emerged as a promising technique with the potential to dominate future generations of broadband wireless communications systems. In this paper, we propose an OFDM modulation scheme combined with distributed space-frequency codes (DSFC) based upon a hybrid relay selection protocol. The DSFC...
