This paper considers a wireless power transfer system with multiple antennas by using the multicarrier signal waveforms. A prior art optimizes the waveform with the channel state information at the transmitter (CSIT) to improve the energy harvesting efficiency of the receiver with the non-linear model. The impact of the imperfect CSIT on the energy harvesting capability is studied as a function of...
The 3GPP have standardized the sidelink channels for the long term evolution (LTE) to support device-to-device (D2D) and vehicular-to-vehicular (V2V) communications. This paper investigates the carrier freuqncy offest (CFO) estimation and sidelink ID set detection by using a primary sidelink synchronization signal (PSSS) when a large CFO occurs. We compare the PSSS in the standard and its modified...
We consider a wireless-powered multi-pair relaying network with a multi-antenna relay which applies the energy beamforming (BF) for wireless powering and zero-forcing BF for the information relaying. For the network, power and time allocation problems are tackled to maximize the minimum achievable rate among the device pairs with the instantaneous channel station information (CSI) and statistical...
We consider resource allocation for a multi-pair decode-and-forward relay network, where a massive antenna relay powers the sources through energy beamforming (BF) in one phase and assists wireless information transfer (WIT) through zero-forcing receive and transmit BF in two subsequent phases. For the network with imperfect channel state information, we analyze the average achievable rates of the...
