Radio detection and ranging in communication networks
Order-of-magnitude accuracy improvements for self-driving cars and other applicationsBackground Vehicular RADARs have high device cost, since they exploit large spectrum resources at millimeter-wave frequencies (24 GHz and 77 GHz) with tightly-coupled analog circuits and advanced antenna configurations on expensive process technology to overcome link...
Ultrathin conformal mantle cloaks for invisibility and antenna applications
Background Significant interest in reducing the antenna blockage in high-complexity or crowded communication systems has been recently highlighted by several authors. In this context, reducing the electromagnetic presence of an antenna or a sensor by tailoring its geometry, loading, or cover has been explored and demonstrated in several examples. Recently,...
Energy-efficient MIMO systems
Background It is generally accepted that Multiple-Input Multiple-Output (MIMO) achieves better energy efficiency than Single-Input Multiple-Output (SIMO) thanks to spatial multiplexing gain. However, when circuit power is considered, MIMO may consume more power than SIMO at low spectral efficiency. This is because MIMO has multiple antennas and transmission...
