Abstract The Cognitive Radio Network (CRN) in 5G heterogeneous network has trade-off
between energy efficiency and spectrum sensing efficiency. Energy Efficiency is important …

We consider an energy-harvesting cognitive radio system where the secondary transmitter
harvests energy. This system operates under an energy causality constraint mandating that …

Abstract 5G Cognitive Radio Network (CRN) has a drawback in energy efficiency and
spectrum sensing trade-off. When it comes to building the cognitive radio, it is essential to …

Traditional spectrum sensing methods require that a secondary user (SU) senses the
spectrum at the beginning of each time slot. A closer look at the network activities of a …

In cognitive radio, spectrum sensing is used to find the white spectrum or protect the primary
user from interference caused by the secondary user (SU). There are two conventional …

We propose a multi-layer spectrum sensing optimisation algorithm to maximise sensing
efficiency by computing the optimal sensing and transmission durations for a fast changing …

In this letter, we present a new accurate closed-form approximation of the performance of a
finite number of samples based on energy detector (ED) using multiple correlated receiving …

In this paper, a collaborative energy-harvesting cognitive radio (CR) network is considered
such that the transmitter of the secondary user (SU) is allowed to harvest signal energy of …

In this paper we present new results on the problem of finding the best channel sensing
order for multi-channel Dynamic Spectrum Access (DSA) networks. We start with the general …

Multi-user cognitive radio networks have been considered in the literature recently.
However, there is no analytical framework which can provide a model in order to derive the …
