Implementing the optimal bounding ellipsoid algorithm on a fast processor

It is shown that the optimal bounding ellipsoid (OBE) algorithm for identifying an ARMAX system can be formulated as a conventional weighted recursive least squares estimator with special weights. In this framework the OBE can be implemented using contemporary algorithms developed for least squares solutions on systolic machines. An example of a systolic processor for OBE is given, and computational complexity issues are considered.<<ETX>>
