  • Abstract
    We derive compact systolic structures for the transcoding of critically sampled modulated lapped transforms (MLT´s) of equal and rational sizes. The structures include two modules for DCT-IV computation and an intermediate module for all windowing/reordering operations. The proposed structure is highly regular and provides theoretical and practical insights for this transcoding problem.
