Power Allocation for Statistical QoS Provisioning in Opportunistic Multi-Relay DF Cognitive Networks - 2013 PROJECT TITLE :Power Allocation for Statistical QoS Provisioning in Opportunistic Multi-Relay DF Cognitive Networks - 2013ABSTRACT:In this letter, we propose a power allocation scheme for statistical quality-of-service (QoS) provisioning in multi-relay decode-and-forward (DF) cognitive networks (CN). By considering the direct link between the source and destination, the CN first chooses the transmission mode (direct transmission or relay transmission) based on the channel state information. Then, according to the determined transmission mode, efficient power allocation will be performed under the given QoS requirement, the average transmit and interference power constraints as well as the peak interference constraint. Our proposed power allocation scheme indicates that, in order to achieve the maximum throughput, at most two relays can be involved for the transmission. Simulation results show that our proposed scheme outperforms the max-min criterion and equal power allocation policy. Did you like this research project?
