A high speed and reduced-area 2-D discrete wavelet transform (2-D DWT) architecture is proposed and the design is simulated. Initially modifications are made to the lifting scheme, and the intermediate results are recombined and stored to reduce the number of pipelining stages. The architecture uses three basic 1D-DWT image processing elements. The proposed architecture only requires less regis...

Radio frequency fingerprint (RFF) identification distinguishes wireless transmitters by exploiting their hardware imperfection that is inherent in typical radio (RF) front ends. This can reduce the risks for identities of legitimate devices being copied, or forged, which also occur conventional software-based systems. paper analyzes feasibility device unique non-linear memory effect transmitter...

Abstract This research concerns the estimation of latent linear or polychoric correlations from fuzzy frequency tables. Fuzzy counts are particular interest to many disciplines including social and behavioral sciences especially relevant when observed data classified using categories—as for socioeconomic studies, clinical evaluations, content analysis, inter-rater reliability analysis—or imprec...
