Abstract
ADSL (asymmetric digital subscriber line) transmission technology meets Internet access requirement quite well and offers telephone companies a technology for connecting virtually all Internet users at megabit rates. The ANSI (American National Standards Institute) proposes discrete multitone (DMT) modulation with DFT (discrete Fourier transform) bases as the carriers for the ADSL system. Recently, discrete wavelet multitone modulation has been studied with non-blind and blind equalization schemes. We propose an entirely different approach which combines the multitone modulation and optimal orthonormal subband coding.
