Abstract

An analysis of band energy distributions in perfect reconstruction (PR) multirate systems is presented, and the effects of aliasing are evaluated. A performance measure called nonaliasing energy ratio (NER) is defined. The merit of the new measure is emphasized with performance comparisons of the popular block transforms and two-band PR-QMF based hierarchical filter banks. It is shown that the new measure complements the widely used energy compaction measure and is consistent with the subjective performance results.
