    On the Dual-Tree Complex Wavelet Packet and M-Band Transforms
    Download  taco.poly.edu
    The two-band discrete wavelet transform (DWT) provides an octave-band analysis in the frequency domain, but this might not be "optimal" for a given signal. The discrete w...

    Nonlinear and Nonideal Sampling: Theory and Methods
    Download  webee.technion.ac.il
    We study a sampling setup where a continuous-time signal is mapped by a memoryless, invertible and nonlinear transformation, and then sampled in a nonideal manner. Such scenarios a...
