SYSTEM AND METHOD FOR SENSING DISTANCE AND/OR MOVEMENT USING COMMUNICATION OVERLAY
A method for measuring a separation distance to a target object using a communication signal includes transmitting from a first device, via a transmitter of the first device, a communication signal including a first bit pattern encoded therein. The method also includes receiving, via a processor on the first device, a copy of the communication signal prior to encoding and receiving, via a receiver of the first device, an echo based on the transmitted communication signal. The received echo is decoded and the method includes identifying, via the processor, the first bit pattern in the copy of the communication signal and identifying, via the processor, the first bit pattern in the decoded echo. Then the method determines, via the processor, a time of flight of the first bit pattern based on identifying the first bit pattern in each of the copy of the transmitted communication signal and in the received echo, and performs, via the processor, an action based on the determined time of flight.
