METHOD OF OPERATION AND SYSTEM FOR DISCRIMINATION BETWEEN MULTIPLE SURFACE ACOUSTIC WAVE IDENTIFICATION TAGS

摘要

The present invention provides a system for discriminating between coded responses from multiple SAW identification tags and a method of operating su ch system. In one embodiment the system provides for (1) a SAW tag reader subsystem that detects coded responses from the tags to an interrogation pulse; and (2) a coded response analyzing subsystem (140), coupled to the SA W tag reader subsystem (130), that employs signal processing techniques to separate portions of the coded responses and generates possibilities for remaining portions of the coded responses.
