In this paper, we propose a two-way relaying scheme using digital network coding in an
underlay cognitive radio network. In the proposed scheme, the transmit antenna selection …

For a cognitive radio relaying network, we propose a cross-layer design by combining
information-guided transmission at the physical layer and network coding at the network …

In this paper, a full duplex relay (FDR) based cognitive radio (CR) system is proposed with
two secondary source nodes and two secondary destination nodes. The concept of physical …

This letter introduces a new cognitive radio system employing the two-path amplify-and-
forward relaying scheme. In the proposed system, the primary user (PU) transmitter …

In this paper, we propose an underlay two‐way relaying scheme with the successive
interference cancellation (SIC) solution in which two secondary sources transmit …

In this paper, we present an optimal scheme for power allocation and relay selection in a
cognitive radio network where a pair of cognitive (or secondary) transceiver nodes …

In this paper, we evaluate performance of a hybrid decode-amplify-forward relaying protocol
in underlay cognitive radio. In the proposed protocol, a secondary relay which is chosen by …

In this paper, a hop-by-hop relay selection strategy for multi-hop underlay cognitive relay
networks (CRNs) is proposed. In each stage, relays that successfully decode the message …

In spectrum sharing systems, a secondary user (SU) is permitted to share frequency bands
with primary user (PU) as long as its transmission does not interfere with the PU's …

In the underlay decode-and-forward (DaF) cooperative cognitive radio (CR) network, an
optimal relay can be selected by the conventional max-min selection on the condition of not …
