Abstract
A mobile communication device equipped for proximity detection may include a transmitter that emits a periodic ultrasound signal, a receiver that detects the periodic ultrasound signal, an intra-frame filter that filters the detected periodic ultrasound signal based on a frame length of the detected periodic ultrasound signal, and a detector that determines a power level of the filtered periodic ultrasound signal to detect if the receiver is located in an undesirable location.
