  • Abstract
    The performance and implementation of the inverse QR algorithm for recursive least squares filtering are examined. This algorithm is based upon an inverse QR decomposition and therefore avoids the highly serial backsubstitution step required in previously derived direct QR approaches. A parallel implementation of the method is discussed and computational wavefronts are displayed. A brief comparison is made with an alternative array structure
