A novel approach to improve noise reduction in the Matrix Pencil Algorithm for chipless RFID tag detection

A chipless radio frequency identification, RFID, tag is a structure that, when excited, scatters a unique signature which is inherent to the structure [1–3]. Data is encoded as natural resonances in the structure and retrieved from the scattered field. Data retrieval is based on Singularity-Expansion-Method (SEM) analysis [4] in the complex frequency domain using target identification techniques.
