Active Scattering for Bandwidth Enhanced MIMO

摘要

Embodiments of a communications system with multiple active scattering devices to service multiple users either indoor or outdoor over same spectrum in a communication network and a method for the system are generally described herein. Signals streams for transmission to users in spoke-and-hub configurations will utilize multiple active scattering devices. Three categories of operational concepts are presented: (1) multiple scattering devices arranged geometrically bundled together to function as active mirrors or retro-directive repeaters, (2) distributed man-made scattering devices placed to enhance channel bandwidth in between a hub and a common service area via frequency re-use, and (3) organizing distributed active scattering devices by remote beamforming for servicing a small common coverage area indoor or outdoor with enhanced bandwidth. All three techniques are for service with enhanced bandwidth and angular resolutions via frequency reuse, and extended service range via coherent operations of scattering devices.
