Abstract

The numerical accuracy and robustness of a systolic QR decomposition post-processor system which computes least squares combination coefficients are investigated. Two versions are compared, one using a Kalman closed-loop feedback arrangement, the other a theoretically equivalent open-loop system. The build-up of round-off error in the post-processor and the ability of the systems to compensate weight vector errors are assessed.
