“…For most existing cooperative OFDM techniques [5,[7][8][9][10]17], the users serving as relays transmit only the data of other users during the cooperation phase. The main difference between the proposed approach and these techniques lies in the fact that each cooperating user transmits a linear combination of the user's own data and also data from the other user.…”

“…In [5], a hybrid forwarding scheme was proposed for cooperative relaying in OFDM-based networks that adaptively decides between AF, DF, or no relaying at all, based on the instantaneous SNR on each subcarrier. An OFDM cooperative scheme for multihop networks was proposed in [7], where in order to achieve full spatial diversity, relay selection is performed on a per-subcarrier basis instead of the entire block. Each subcarrier can determine the best relay independently at each hop, so that different subcarriers experience different paths.…”

“…Simpler, non-DSTC approaches that employ relay selection have been proposed for communication through frequency-selective fading channels. For example, in [17,18], uncoded OFDM is studied, and it was shown that if relay selection is done on a per-subcarrier basis, full spatial diversity can be achieved. However, neither of these OFDM-based relay selection methods were able to exploit the frequency diversity of the ISI channel [19].…”

“…In [10], per subcarrier hybrid cooperation strategies were proposed, with the goal of minimizing the error probability. Methods for subcarrier selection in multihop OFDM systems were developed in [11]. Resource allocation for an OFDMA system where each user is allowed to transmit and receive at the same time, but necessarily on different subcarriers, was considered in [12].…”
