A limited-feedback-based dynamic resource allocation algorithm is proposed for a relay cooperative network with orthogonal frequency-division-multiplexing (OFDM) modulation. A communication model where one source node communicates with one destination node assisted by one half-duplex decode-and-forward (DF) relay is considered in this paper. We first consider the selective DF scheme, in which some...
It has been shown that channel state information (CSI) at transmitter can significantly increase the performance of a relay system. However, most of the existing designs assume perfect CSI at the transmitters. Since most practical systems can only obtain partial CSI at the transmitters, it is necessary to analyze the relay channels with limited CSI feedback. Our objective in this paper is to find...
