Title:
METHOD AND APPARATUS FOR SELF-BEATING SCHEME FOR FMCW-BASED PROXIMITY DETECTOR FOR 5G MMW DEVICES
Document Type and Number:
WIPO Patent Application WO/2020/086170
Kind Code:
A3
Abstract:
Aspects of the present disclosure provide a simplified solution for proximity detection of an object in a wireless communication that does not require complex hardware to maintain mutual coupling reference signal. Specifically, in accordance with aspects of the present disclosure, the received signal that may include the mutual coupling signal and target signal may be multiplied by itself to extract the delay information associated with the target signal. The techniques outlined here may provide a greater robustness to variations of mutual coupling induced by phone covers, for example, being added by the user.
