Title

Noise-Like Transducers For Ultra Wide Band Saw Correlators

Abstract

This paper presents the development of sampled Gaussian noise transducers for surface acoustic wave (SAW) correlation filters for use in ultra-wideband (UWB) communications and tagging. The orthogonal frequency coded (OFC) SAW correlator concept was previously demonstrated using a uniformly weighted OFC coded dispersive transducer in conjunction with a wideband apodized transducer. The interdigital SAW transducer can accurately represent the noise-signal by electrode apodization. For an ideal-Gaussian white noise signal, there are no correlation sidelobes and cross-correlation of other codes is extremely small. For a finite truncated white-noise Gaussian signal, that is also frequency band-limited, the auto-correlation sidelobes are produced, a function of the signal time bandwidth product. © 2012 IEEE.
