ISO/IEC 14443 VHBR: influence of the proximity antennas on the PCD-to-PICC data link performance

The demand for faster transmission rates in radio frequency identification has led to the adoption of phase-shiftkeying (PSK) modulations for the communication between the proximity coupled device (PCD) and the proximity integrated circuit card (PICC). This paper derives a transmission model to analyze the intersymbol interference generated by the PCD-to-PICC coupled antennas. An equalizer structure is then introduced and performance compared against previous generations of very-high bit rate systems using amplitude shift keying. It concludes that PSK modulations proposed for VHBR can be robust even when the resonance of the antenna circuits is relatively high.
