We conceive a fair resource allocation scheme for multiuser multiple relay aided OFDMA networks. We study the optimization problem of subcarrier assignment under outage constraints. The outage constraints are transformed into the power constraints of the relays. A priority based proportional fairness multiuser scheduling approach is employed to achieve the complimentary rate fairness of all users...
We investigate the outage performance of multi-antenna cognitive wireless relay networks where source nodes transmit information to their destinations via two hops facilitated by intermediate cognitive nodes able to acquire spectrum holes. In particular, we conduct an outage performance analysis for a decode-and-forward (DF) relaying system under three scenarios which are depending on the spectrum...
The outage performance for the opportunistic amplify-and-forward relaying strategies under Nakagami-m fading channels is investigated in this paper. A closed-form expression for the outage probability is derived. Simulation results verify our theoretical solutions.
We investigate the outage performance in the Nakagami fading for the decode-and-forward relaying with multiple receive antennas at the destination. A close-form expression for the outage probability is derived. Simulation results demonstrate our theoretical solution.
Wireless relaying is one of the promising solutions to overcome the channel impairments and provide high data rate coverage that appears for beyond 3G mobile communications. In this paper we present an end to end BER performance analysis of dual hop wireless communication systems equipped with multiple decode and forward relays over the Rayleigh fading channel with relay selection. We select the best...
