Round-Trip Energy Efficiency of Wireless Energy Powered Massive MIMO System With Latency Constraint
IEEE Communications Letters, 2017We consider a massive MIMO system with frequency-division duplex, where a base station (BS) transfers energy to multiple users in the downlink and the users simultaneously transmit information to the BS in the uplink using the harvested energy.

Energy efficient ranging in wireless sensor networks via a new time slot-based round-trip algorithm
2014 IEEE Aerospace Conference, 2014This paper introduces a ranging algorithm for wireless sensor networks. Here, a novel time slot based technique is applied for ranging of sensor nodes within the clustered sensor network. The proposed technique avoids clock synchronization of sensor nodes by exploiting the round-trip time-of-flight measurements.

Nanoscale, 2013
β-FeOOH nanorod (NR) catalysts prepared by ultrasonic-irradiated chemical synthesis enabled lithium-air cells to have high round-trip efficiency and extremely low overpotential as well as an outstanding rate capability. Good catalytic activities of the β-FeOOH NR bundle could be ascribed to its crystal structure, which consists of 2 × 2 tunnels formed ...
