In this paper, we study the joint allocation of three types of resources, namely, power,
subcarriers and relay nodes, in multi-relay assisted dual-hop cooperative OFDM systems. All …

This paper investigates subcarrier and power allocation in multiuser OFDM. The aim is to
maximize the overall rate while achieving proportional fairness amongst users under a total …

This paper proposes a relay-based scheme where a fixed number of relays are utilized to
design an OFDM cooperative protocol. By exploiting limited feedback from the destination …

In this paper, we propose a real-time subcarrier, bit, and power allocation algorithm for
orthogonal frequency-division multiplexing-based multiuser communication systems in …

Adaptive resource allocation to exploit multiuser diversity and spacial diversity in OFDMA
relay-aided cooperative cellular networks is studied. Assuming that the BS has all the …

We investigate the resource allocation problem for an OFDM cooperative network with a
single source-destination pair and multiple relays. Assuming knowledge of the …
