The algorithm is based on the RLS covariance matrix management, by making use of the covariance resetting in a different way. The approach provides a kind of attractor that absorbs all nonmodeled dynamics. In order to demonstrate its effectiveness, the proposed algorithm is applied to simulated signals and its performance is compared with other conventional methods.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-28T13:57:51Z No. of bitstreams: 1 Almeida.pdf: 480281 bytes, checksum: 8d032d579d9c5d1bb20bd17e1dac2933 (MD5)Approved for entry into archive by Fatima Cleômenis Botelho Maria (botelho@ufba.br) on 2013-01-30T12:58:24Z (GMT) No. of bitstreams: 1 Almeida.pdf: 480281 bytes, checksum: 8d032d579d9c5d1bb20bd17e1dac2933 (MD5)Made available in DSpace on 2013-01-30T12:58:24Z (GMT).
