Recently, a considerable amount of attention is being given to the use of wavelets for modulation and equalization. In this correspondence, we present an equalization algorithm for a wavelet packet-based, modulation scheme. A nonideal channel can he divided into a set of bands, where each band can be approximated as a simple attenuation and delay channel, Wavelet packets, being narrowband and orthonormal, are a natural choice for realizing such bands. Thus, if the data sequence is used to modulate a set of wavelet packets, the equalization problem reduces to that of determining the delay introduced by the channel for each of the wavelet packets (if the wavelet packets do not overlap in the frequency domain) and possibly a change of sign in ...
