Abstract: The objective of this paper is to present the subject of wavelets from a filter-theory perspective, which is quite familiar to electrical engineers. Such a presentation provides both ...

The Wavelet Transform Modulus Maxima (WTMM) method is a powerful tool in signal processing and fractal analysis. It allows for the detection of singularities in signals—points where the signal behaves ...

ABSTRACT: The BER performance for an optimal circular 16-QAM constellation is theoretically derived and applied in wavelet based OFDM system in additive white Gaussian noise channel. Signal point ...

ABSTRACT: We present wavelet bases made of piecewise (low degree) polynomial functions with an (arbitrary) assigned number of vanishing moments. We study some of the properties of these wavelet bases; ...
