Performance of a Cognitive Relay Network under AF Relay Selection Scheme with Imperfect Channel Estimation
In this paper outage performance of a secondary user (SU) is evaluated under an amplify and forward (AF) relay selection scheme with an imperfect channel state information (CSI) while the SU shares spectrum in an underlay cognitive radio network (CRN). In underlay, the SU coexists with primary user (PU) in the same band provided the interference produced by SU at the PU receiver is below an int...
متن کاملSecurity-reliability performance of cognitive AF relay-based wireless communication system with channel estimation error
In this paper, both the security and the reliability performance of the cognitive amplify-and-forward (AF) relay system are analyzed in the presence of the channel estimation error. The security and the reliability performance are represented by the outage probability and the intercept probability, respectively. Instead of perfect channel state information (CSI) predominantly assumed in the lit...
متن کاملRelay Selection Scheme for AF Relay Network based on Cost Function Criterion
An amplify-and-forward (AF) wireless relay network consisting of a one-source-one-destination node pair and cooperative multiple N relay nodes is proposed in three adverse wireless communication environments, i.e., jamming, node geometry, and channel uncertainty. Based on the minimum mean square error (MMSE) criterion, the optimal amplifying relay matrix in three adverse wireless environments w...
متن کاملDistributed Relay Selection and Channel Choice in Cognitive Radio Network
In this paper, we study the cooperative communications where multiple cognitive radio (CR) transmit-receive pairs competitive maximize their own throughputs. In CR networks, the influences of primary users and the spectrum availability are usually different among CR users. Due to the existence of multiple relay nodes and the different spectrum availability, each CR transmit-receive pair should ...
متن کاملOpportunistic DF-AF Relaying Selection in Multiple Access Relay Channel
This paper presents an outage performance of multiple access relay channel (MARC) for decode-and-forward (DF) relay and amplify-and-forward (AF) relay selection. We consider the multiple-access relay channel with two source nodes, one relay node and one destination node. In MARC, multiple sources transmit to a common destination simultaneously with the assistance of a single relay. In a relayin...
