Artificial Noise Aided Secrecy Information and Power Transfer in OFDMA Systems

Artificial Noise Aided Secrecy Information and Power Transfer in OFDMA Systems Abstract: In this paper, we study simultaneous wireless information and power transfer (SWIPT) in orthogonal frequency division multiple access (OFDMA) systems with the coexistence of information receivers (IRs) and energy receivers (ERs). The IRs are served with best-effort secrecy data and the ERs harvest […]


Optimal Relay Probing in Millimeter Wave Cellular Systems with Device-to-Device Relaying

Optimal Relay Probing in Millimeter Wave Cellular Systems with Device-to-Device Relaying Abstract: Millimeter-wave (mmWave) cellular systems are power-limited and susceptible to blockages. One promising approach to increasing mmWave connectivity and range is to use relays. Device-to-device (D2D) communications open the door to the vast opportunities of D2D relaying for mmWave cellular systems. In this correspondence, […]
