In this letter, we analyze the performance of cognitive amplify-and-forward multirelay
networks with active direct link in the presence of relay transceiver hardware impairments …

In this paper, we analyze the performance of a cognitive decode-and-forward multi-relay
network (CDFMRN) with a direct link under the joint impact of transceiver hardware …

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 letter, exact outage probability of decode-and-forward (DF) and incremental DF (IDF)
relaying are respectively derived over underlay cognitive relay networks. Particularly, we …

We examine the impact of multiple primary transmitters and receivers (PU-TxRx) on the
outage performance of cognitive decode-and-forward relay networks. In such a joint …

This paper analyzes the outage performance of cognitive relay networks operating in the
same frequency band of a primary transceiver. Different from previous works, opportunistic …

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 …

In the presence of the primary user's interference, the outage probability of a dual-hop
decode-and-forward (DF) cognitive relay network (CRN) over Rayleigh fading channels is …

This letter considers amplify-and-forward (AF) cognitive relay networks with interference
power constraint and transmit power constraint in a spectrum-sharing context. In particular …

This study first modifies the traditional partial relay selection in cooperative cognitive
networks to prevent error propagation and then proposes exact and asymptotic outage …
