Abstract
A matrix decomposition structure of a two-channel quadrature mirror filter bank, including an analysis filter part, a synthesis filter part, the filter part includes an Emodule, an X module, a Y module, a Z module, an input port and an output port. The X module takes a value of the input port as an input of a multiplier, and the Emodule delays the input. An output of the Xmodule passes through the Y module and then is used as an input of the Z module, and outputs of the Z module and the Emodule are added and then output from the output port, and pass through a middle part to enter the synthesis filter part.
