Abstract
In this paper, multisine excitation signals are used to extend the reading range of commercial RFID readers. To do so, a commercial reader is equipped with an external multisine front-end that implements previous mathematical proposals. A reading range improvement is achieved when compared with conventional single carrier approaches, even with the same average power being transmitted. A reading range improvement of near 43% is obtained for a 8-tones multisine signal with 2MHz tone separation.
