This paper evaluates the multiple-input multiple-output underlay cognitive multihop relay
networks with short-packet communications, where general and practical scenarios are …

In this work, we investigate short-packet communications for multiple-input multiple-output
underlay cognitive multihop relay networks with multiple primary users, where transceivers …

In the underlay spectrum sharing approach, cognitive radios have limited coverage area to
keep interference protection for the licensed users. Multiple cooperative relays have shown …

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 …

We analyze relay selection for an underlay cognitive radio (CR) two-way relay network
(TWRN) with zero-forcing (ZF) transmission and receiving. The source and the destination …

Amplify-and-forward (AF) two-way relay networks (TWRNs) have become popular to provide
spectrally efficient communication when range extension or energy efficiency is needed by …

In this paper, we examine the performance of multiple-input multiple-output (MIMO) cognitive
amplify-and-forward (AF) relay systems with maximum ratio transmission (MRT). In …

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 …

In this paper, we consider bidirectional decode-and-forward (DF) buffer-aided relay
selection and transmission power allocation schemes for underlay cognitive radio (CR) relay …

In this paper, we propose a multi-hop multiple input multiple output (MIMO) decode-and-
forward relaying protocol in cognitive radio networks. In this protocol, a multi-antenna …
