Vector-channel lattice filters for the delta operator: Complete derivation

  • Published:

Abstract

The numerical difficulties associated with high sampling rates have been the main motivation for the recent interest in application of delta-operator formulation in adaptive identification and control techniques, as an alternative to the traditional shift operator. In this article, the derivation of the vector-channel lattice algorithm for least-squares parameter estimation of an input/output model based on the delta operator is presented. Since the vector-channel formulation is a generalization of the standard multichannel forms, results presented here apply to the multichannel lattices as a special case. In addition to the basic derivation, algorithms for residual errors and autoregressive coefficients, a simple example, and issues regarding implementation are discussed.
