BER Minimization in Relay-Assisted OFDM Systems by Subcarrier Permutation
—We consider relay-assisted communications from a source to a destination based on OFDM. The relay performs subcarrier permutation by exploiting full channel state information (C...

Opportunistic Relaying in Cellular Network for Capacity and Fairness Improvement
— In this paper, we study how the cooperative relaying can improve both capacity and fairness in cellular network. The capacity and fairness have a trade-off relationship, so inc...

An efficient adaptive distributed space time coding scheme for cooperative relaying
A non-regenerative dual-hop wireless system based on distributed Alamouti space-time coding is considered. It is assumed that each relay retransmits an appropriately scaled space-t...
