摘要
A method, apparatus, and a computer program product for generating a set of jointly optimized linear signal processing filters and subband filters for processing digital data on a computer system are presented. In general, the invention performs the operations of determining a design scheme for at least one linear signal processing filter; determining a design scheme for at least one subband filter; and relating the design schemes for the at least one linear signal processing filter and the at least one subband filter in order to determine a relationship therebetween. The relationship provides criteria for optimization (e.g. maximizing data compression while minimizing processing requirements). Next, the design schemes are jointly adjusted using the relationship to optimize the criteria for optimization and generates an optimized linear signal processing filter/subband filter set to provide improved data processing performance.
