Abstract :
A block transform packet (BTP) is an orthonormal block transform which is constructed from conventional block transforms and represents an arbitrary tiling of the time-frequency plane. Unlike the progenitor transforms, the BTP has the ability of time-localization and is capable of dealing with non-stationary signals. This paper describes procedures for signal decomposition using the BTP in an adaptive way. Three examples show the adaptive compression efficiency over the DCT
