Patent ID: 7028060

Claim:
A method for generating a set of jointly optimized linear signal processing filters and subband filters for processing digital data on a computer system, the method comprising the steps of: determining a design scheme for at least one linear signal processing filter, with the design scheme for at least one linear signal processing filter dependent upon at least one performance characteristic; determining a design scheme for at least one subband filter, with the design scheme for at least one subband filter dependent upon at least one performance characteristic; relating the design scheme for the at least one linear signal processing filter and the design scheme for the at least one subband filter in order to determine a relationship therebetween; and jointly adjusting the design scheme for the at least one linear signal processing filter and the design scheme for the at least one subband filter using the relationship therebetween to optimize at least one desirable performance characteristic; whereby a set of linear signal processing filters and subband filters are optimized together in order to provide better data processing performance with regard to the at least one desirable performance characteristic than would be available without optimization.
