Abstract
A digital data system () provides 1-D, 2-D and 3-D capability and multi-band channel capability. Improved filter banks are created by generating a filter bank having an analysis portion and synthesis portion and obtaining wavelet coefficients () for each portion. The wavelet coefficients are expressed in a format capable of canonical signed digit (CSD) representation, such as integers (). The canonical signed digit (CSD) representation is controlled by a value, N, selected to control resolution of the CSD coding. Optimized CSD-coded wavelet coefficients are used as filters for data signals ().
