Abstract

Provided is a method and a system for multi-channel acoustic communication and sensing. For example, there is provided a system that includes a processor and a memory. The processor, when executing instructions from the memory, can perform certain operations. The operations can include classifying a motion detected near an ultrasonic receiver based on a Doppler shift observed in a signal measured by the ultrasonic receiver. The classifying can further include detecting a side lobe in a power spectrum of the signal to indicate that the motion has been detected.
