We consider an energy‐efficiency multichannel cognitive radio (CR) where the secondary
user (SU) can harvest the signal energy from the primary user (PU) to supply the power …

In cognitive radio (CR), the spectrum sensing of the primary user (PU) may consume some
electrical power from the battery capacity of the secondary user (SU), yielding to decrease …

In this paper, a simultaneous cooperative spectrum sensing and energy harvesting model is
proposed to improve the transmission performance of the multichannel cognitive radio. The …

In cognitive radio (CR), the secondary user (SU) may use more battery energy to perform
spectrum sensing, thus decreasing the transmission energy. In order to guarantee the …

A decentralized channel access strategy is proposed for a multichannel low-power cognitive
radio (CR) system. CRs are equipped with rechargeable batteries to harvest radio-frequency …

This paper focuses on the problem of sensing throughput optimization in a fading multiple
