Latest Patents
One of his key patents is titled "Matrix decomposition structure of two-channel quadrature mirror filter bank and coefficient design method thereof." This invention presents a matrix decomposition structure that includes an analysis filter part and a synthesis filter part. The filter part consists of an E-module, an X module, a Y module, a Z module, an input port, and an output port. The X module utilizes the value from the input port as an input for a multiplier, while the E-module delays the input. The output from the X module is processed through the Y module and subsequently serves as an input for the Z module. The outputs from the Z module and the E-module are combined and then output from the output port, passing through a middle part to enter the synthesis filter part. This innovative design enhances the efficiency and performance of filter banks.
