Abstract
A Programmable Surface Acoustic Wave (PSAW) correlator pair using Binary Phase Shift Key (BPSK) modulation and an 11-bit Barker code sequence is proposed to increase the security levels of wirelessly transmitted network data in the 2.45 GHz WiFi frequency band. Due to the unique properties of SAW correlator’s interdigital transducer (IDT) fingers, their orientation, and the alternating polarity between sets of IDT fingers, they are well suited for BPSK encoding applications. This encryption is made possible with the use of well-matched PSAW correlator pairs that encode RF burst signals to produce a high auto-correlation vs. cross-correlation signal. This encrypted signal is then decoded by passing it through a reverse coded PSAW correlator to remove the modulation encryption, leaving the original data signal. The critical parameters of the author’s proposed design are presented, including the piezoelectric substrate material selection, relevant equations for critical parameter, and the final proposed design.
