Reader and response control system for discrimination between multiple surface acoustic wave identification tags and method of operation thereof

摘要

A system for discriminating between coded responses from multiple SAW identification tags and a method of operating such system. In one embodiment the system provides for a SAW tag reader subsystem that detects coded responses from the tags to an interrogation pulse; and a coded response analyzing subsystem, coupled to the SAW tag reader subsystem, that employs signal processing techniques to separate portions of the coded responses and generates possibilities for remaining portions of the coded responses.
