We discuss the code reading error probability (EP) in the radio frequency identification (RFID) surface acoustic wave tags with pulse position coding and peak-pulse detection. EP is found in the most general form assuming M groups of codes with N slots each and allowing individual signal-to-noise ratios (SNRs) in each slot. We show that if the RFID tag is designed such that the spurious responses are attenuated on more than 20 dB below On-pulses, then EP can be achieved at the level of 10 −8  (one false per 10 8  readings) with SNR > 17 dB for any reasonable M and N.
