Abstract

The fast implementation of arbitrary-length cosine-modulated filter bank is investigated. By using the linear phase property of the prototype filter, a more efficient implementation structure is obtained for the filter bank. In the new implementation, 2 × 2 lossless lattices are used instead of 2 × 1 ones in the traditional implementation with the number reduced by half.
