RLS was discovered by Gauss but lay unused or ignored until 1950 when Plackett rediscovered the original work of Gauss from 1821. In general, the RLS can be used to solve any problem that can be solved by adaptive filters. For example, suppose that a signal is transmitted over an echoey, noisy channel that causes it to be received as where represents additive noise. The intent of the RLS filter is to recover the desired signal by us… WebExample Applications: Kalman Filter v/s Recursive LS • Kalman filter: Track a moving object (estimate its location a nd velocity at each time), assuming that velocity at current time is velocity at previous time plus Gaussian noise).
