The paper presents practical and effective algorithms to calculate the Toeplitz/Hankel matrix by a vector product that are recursiveless modification of Karatsuba's method. Unlike traditional algorithms, in this case using the FFT is not required. Realization of the developed algorithms involves the use of unconventional ways of choosing the elements of the… (More)

In paper a rationalized approaches to Discrete Wavelet Transform (DWT) coefficients computing, based on modified algorithm of DWT base operation execution, with less multiplication operations are presented. Those several intuitive ways allow to decrease computational complexity of hardware operational units for DWT basic operation computation and provide… (More)
