Abstract :
A few fast tracking recursive least squares (RLS) algorithm for time-varying systems is presented. The new algorithm is based on an innovative variable forgetting factor with a unity zone and its extra computational burden is trivial compared with the standard RLS algorithm. Fast tracking and low parametric error variance properties are verified via computer simulations.
