چکیده

In this paper, the outage performance is investigated for cognitive dual-hop relay networks with amplify-and-forward (AF) relay and selection combining (SC) receiver at the destination under spectrum sharing constraints on primary user (PU) over independent and identically distributed (i.i.d.) Nakagami-m fading channels. We derive an exact closed-form expression for the outage probability (OP) of the considered system under the peak interference power Ip at the primary user, and the impact of the PU location on the OP performance is studied also. Moreover; the effects fading severity for the two hops on the OP is investigated also for this cognitive relay network (CRN).

Underlay Cognitive Networks with Partial Relay Selection and Primary-User Interference

Most related works addressing cognitive relaying networks focus on the impact of the interference constraint imposed by the primary receivers on the performance of the secondary network, while neglecting the interference coming from the primary transmitters. In this paper, we assess the outage performance of a cognitive relaying network composed by a source communicating with a destination unde...

Exact Outage Probability of Cognitive Underlay DF Relay Networks with Best Relay Selection

In this letter, we address the performance analysis of underlay selective decode-and-forward (DF) relay networks in Rayleigh fading channels with non-necessarily identical fading parameters. In particular, a novel result on the outage probability of the considered system is presented. Monte Carlo simulations are performed to verify the correctness of our exact closed-form expression. Our propos...

Performance Analysis of Relay Subset Selection for Amplify-and-Forward Cognitive Relay Networks

Cooperative communication is regarded as a key technology in wireless networks, including cognitive radio networks (CRNs), which increases the diversity order of the signal to combat the unfavorable effects of the fading channels, by allowing distributed terminals to collaborate through sophisticated signal processing. Underlay CRNs have strict interference constraints towards the secondary use...

Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

Cognitive Radio Networks with Best Relay Selection Method

In this paper, we propose a cognitive transmission scheme with the best relay selection in a multiple-relay cognitive radio network to improve the secondary transmission performance while guaranteeing the quality-of-service (QoS) of the primary transmissions. We derive the closed-form expression of outage probability for the secondary transmissions, called Secondary outage probability, with the...
