Abstract

Building on recently introduced multidimensional signalling techniques, a multirate wavelet based modulation format is presented which can utilize existing channels designed for conventional QAM. Customizable wavelet packet basis functions are employed as novel pulse shapes upon which independent QAM data at lower rates are placed. The advantages include dimensionality in both time and frequency for flexible channel exploitation and an efficient all digital filter bank implementation.
