Abstract

In this work, better wavelet packet tree structures are searched to reduce the sum of ISI and ICI powers (integrated power) in Daubechies wavelet-based OFDM system over a practical two path low-voltage powerline channel or two way multipath channel. Better wavelet tree structures are obtained by using a brute-force algorithm. Results show that better wavelet packet tree structures perform better than conventional Mallat structures for the same bandwidth occupancy.
