摘要：
A new solution to the numerical instability of fast recursive least squares adaptive filter algorithms is presented. Using interval arithmetic, an error analysis is effectively performed in parallel with the computations of the algorithm. If necessary the algorithm will be rescued, preventing divergence. This is shown in software simulations and in a hardware implementation of an adaptive equaliser.
