Abstract
The complexity of a plurality of signals in a first domain are characterized. A transform is selected in accordance with the complexity of the plurality of signals, wherein the selected transform is one of a plurality of transforms having differing complexities. The selected transform is applied to the plurality of signals to generate a plurality of transformed signals in a second domain.
