In this paper, a framework for power allocation of downlink transmissions in orthogonal frequency division multiple access-based decode-and-forward cellular relay networks is investigated. We consider a system with a single base station communicating with multiple users assisted by multiple relays. The relays have limited power which must be divided among(More)
In this paper, a framework for power allocation is presented for downlink transmissions in an OFDMA-based cellular relay network. We consider a system with a single base station communicating with multiple users assisted by multiple relays. The relays have limited power which must be divided among the users they support in order to maximize the data rate of(More)
Wireless communication networks have significantly grown in the past few years. These networks are required to meet the expectations of all users irrespective of their locations. Having high data rate connectivity and overcoming capacity degradation in a cell edge area are examples of these expectations. To satisfy these increasing demands, efficient(More)
Wireless communication networks have rapidly developed in the past few years. Increasing number of users demanding wireless access and growing number of wireless applications require a higher link data rate. Wireless communication networks are expected to provide high data rate in the most cost-effective manner. To achieve this objective, high spectral(More)
