Abstract

"This paper compares the transients of the constrained RLS (CRLS) algorithm with the generalized sidelobe canceller (GSC) employing an RLS algorithm. It is shown that the requirement for transient-equivalence is satisfied by the GSC structure using proper initialization, and any restriction concerning orthogonality of the matrices involved may be relaxed. This result differs from the more restrictive case for transient-equivalence of the constrained LMS (CLMS) algorithm and the GSC employing LMS algorithm. Simulations in beamforming and system identification applications confirms the theoretical results."
