High-speed wireless network interfaces are among the most power-hungry components on mobile systems that rely on battery for energy supply and passive means for heat dissipation. This is particularly true for MIMO network interfaces which use multiple RF chains simultaneously. In this paper, we present a novel power management mechanism for MIMO network interfaces on mobile systems, called ante...

Spatial modulation (SM) is a transmission scheme that uses multiple transmit antennas but only one transmit RF chain. At each time instant, only one among the transmit antennas will be active and the others remain silent. The index of the active transmit antenna will also convey information bits in addition to the information bits conveyed through modulation symbols (e.g., QAM). Pseudo-random p...

A transfer-learning-based method for accelerating power-only calibration of phased array antennas by combining the conventional theory with deep learning is presented in this communication. The existing methods either require a significant number measurement cycles or have restrictive phase shifter resolution requirements. proposed uses surrogate model to calibrate all elements one pass without...
