Title:
SYSTEMS AND METHODS FOR OVER-THE-AIR INTERFEROMTER BASED MODULATION
Document Type and Number:
WIPO Patent Application WO/2023/230949
Kind Code:
A1
Abstract:
Aspects of the present disclosure provide an over-the-air (OTA) interferometer that enables redirecting, by a reconfigurable intelligent surface (RIS) to a destination, a signal that impinges the RIS at each of a plurality of time slots, thereby modulating the signal. The RIS is virtually divided into a plurality of RIS portions. In each time slot, phase components to be applied to the plurality of RIS portions are determined based on one or more phase values. The phase values may include an underlying phase related to redirecting a source signal, an additional phase related to data that an input operatively connected to the RIS aims to transmit to the destination by modulating the signal being redirected, and/or a further phase related to interference patterns that can help extract the data phase at the destination. The destination may demodulate the received signals based on the signal strength measurements.
