Novel adaptive sliding window algorithm reducing latency for multi-tag chipless RFID systems

The main contribution of this work is to introduce a novel technique for reducing the latency of multi-tag Frequency Coded (FC) chipless RFID systems, which is defined as the time required for the reader to identify the tagged objects within the same interrogation zone. The frequency scanning methodology, windowing and notch detection are the three main processing blocks that significantly affect the overall system latency.
