A novel power allocation scheme for multi-user single-DF-relay networks

Joint optimal resource allocation schemes for downlink cooperative cellular networks over orthogonal frequency division multiplexing carriers

“…In terms, Multi-User OFDM (MU-OFDM) is regarded as a promising technique to obtain high downlink capacities in future cellular networks. On this basis, Wang et al [13] proposed a proportional rate-adaptive resource allocation method for MU-OFDM, so that it allocated the subcarrier and power sequentially between users. The relay channel which was introduced by van der Meulen [14] and was comprehensively studied by Cover and El Gamal [15].…”
