Paper Abstract

Algorithmic engineering provides a rigorous framework for describing and manipulating the type of building blocks commonly used to define parallel algorithms and architectures for digital signal processing. So far, the concept has only been illustrated by means of some relatively simple examples. These relate to the use of QR decomposition by Givens rotations for the purposes of adaptive filtering and beamforming. In this paper we present a much more challenging example whereby the techniques of algorithmic engineering are used to derive the QRD-based lattice algorithm for multi-channel least squares linear prediction. The elegant simplicity of this derivation, which comprises a sequence of straightforward diagrammatic manipulations, serves to demonstrate the potential power of algorithmic engineering as a formal design technique.
