Simultaneous wireless information and power transfer (SWIPT) has recently drawn significant interest for its dual use of radio signals to provide wireless data and energy access at the same time. However, a challenging secrecy communication issue arises as the messages sent to the information receivers (IRs) may be eavesdropped upon by energy receivers (ERs), which are presumed to harvest energy only...
Simultaneous wireless information and power transfer (SWIPT) has recently drawn significant interests for its dual use of radio signals to provide wireless data and energy access at the same time. However, a challenging secrecy communication problem arises in the SWIPT system since the messages sent to information receivers (IRs) may be eavesdropped by energy receivers (ERs), which are presumed to...
This paper considers spectrum sharing for wireless communication between a cognitive radio (CR) and a primary radio (PR). An effective means known in the literature for the CR to protect the PR is by applying the so-called interference-temperature constraint, under which the CR is allowed to transmit regardless of the PR's on/off status provided that the resultant interference power level at the PR...
