This paper investigates the performance of amplify-and-forward (AF) cognitive relay
networks with partial relay selection (PRS) in a spectrum-sharing context. The PRS schemes …

In this paper, we consider amplify-and-forward cognitive relay networks in a spectrum-
sharing environment. We present the performance analysis under two different partial relay …

Cooperative relaying technology has been proved to be one of the most promising
techniques to improve the throughput of CR networks. In this paper, cognitive relay networks …

The outage probabilities (OPs) of cognitive amplify‐and‐forward systems with the
conventional and the switching‐based partial relay selection (PRS) schemes over …

This paper investigates several important performance metrics of cognitive amplify-and-
forward (AF) relay networks with a best relay selection strategy and subject to non-identical …

In this paper, to guarantee the reliable communications of the primary user (PU), we impose
a joint constraints on both average and peak interference power. With multiple relays …

In this paper, we address the problem of maximizing the received signal-to-noise ratio (SNR)
of a relay-assisted secondary network. In particular, a pair of cognitive radio nodes …

In this paper, we propose a cognitive transmission scheme for Amplify-and-Forward (AF) two-
way relay networks (TWRNs) and investigate its joint sensing and transmission …

The exact closed-form expressions for outage probability and bit error rate of spectrum
sharing-based multi-hop decode-and-forward (DF) relay networks in non-identical Rayleigh …

Relay selection is an effective way to achieve considerable performance gains in cognitive
relay networks (CRN). In practice, the best relay may not always be selected, thus the study …
