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