Abstract

The ODR (orthogonal double-rotation) digital lattice filters have desirable properties for VLSI implementation such as local connection, regularity and pipelinability. These filters are also known to exhibit good numerical behavior for finite precision implementation. Although these filters can be pipelined by the cut-set localization procedure, it should be noted that the maximum sample rate obtained by this technique is limited by the feedback computations. In this paper, a pipelining method for the ODR digital lattice filters is proposed, by which the sample rate can be increased at any desired level. The pipelining method is based on the properties of the Schur algorithm, constrained filter design methods, and the polyphase decomposition technique.
