In this paper, we study a wireless-powered communication network (WPCN) scenario, in which a multiple antenna amplify-and-forward (AF) two-way relay coordinates power transfer and information exchange to multiple pairs of users. A harvest-then- transmit protocol is assumed where the relay first transmits energy signals to the users in a power transfer phase. Multi-pair of users, which have rechargeable...
In this paper, we consider a wireless-powered communication network in which a multiple-antenna two-way AF relay transfers power to multi-pair of single antenna users. A harvest-then-transmit protocol is adopted where the relay first broadcasts wireless power to all the users during a power transfer phase. Multiple pairs of users then use the harvested energy to exchange information through the relay...

Wireless power transfer conveniently enables prolonging the lifetime of energy-constrained wireless nodes by means of scavenging the energy of radio-frequency signals. Most existing work on this topic assumes negligible background noise power and focuses only on harvesting the power signal transmitted by the access point (AP). In contract, in this paper we show that in Gaussian-Bernoulli (GB) impulsive...
