Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems)  are possible alternatives to provide security for such applications. In this paper, we consid...

We show that managers have a propensity to disproportionately report total revenues just above base-ten thresholds (e.g., 10 million, 30 1 billion) and examine motives for consequences of this behavior. Focusing on in is important because, despite being unusually prevalent revenue targets set executive compensation contracts, analyst forecasts, management they not been previously explored. also...

This paper studies a new decode-and-forward relaying scheme for a cooperative wireless network composed of one source, K relays, and one destination and with binary frequency-shift keying modulation. A single threshold is employed to select retransmitting relays as follows: a relay retransmits to the destination if its decision variable is larger than the threshold; otherwise, it remains silent...
