USING AUXILIARY S IGNAL TO REMOVE THE SPR CONDI TI ON FROM RECURS1 VE ADAPT1 VE ALGOR1 THMS

The use of adaptive recursive filters and output error identification techniques has been severely restricted by the need to satisfy the so-called SPR condition. In well knm HARP algorithm to remove the SF'R condition by using awiliary signal. It has the merit of simple computational comptexity. This should allow for more widespread use of adaptive recursive filtering and output error sys tem idemt i f ication. this paper a new method is demonstrated on the
