A novel architecture of implementing wavelet transform and reconstruction processor with SAW device based on MSC

We propose to implement wavelet transform and reconstruction processor with surface acoustic wave (SAW) device based on multistrip coupler (MSC). Uniform interdigital transducer (IDT) and reconstruction wavelet IDT were grated on two output tracks of wavelet IDT, respectively. This architecture enables wavelet transform and wavelet reconstruction operation to be simultaneously implemented in one processor. Furthermore, second insertion loss is overcome in wavelet reconstruction processor.
