Blind adaptive H-infinity multiuser detection for CDMA systems with impulsive noise

In this letter, blind adaptive H-infinity multiuser detection is developed by employing a generalized sidelobe canceler (GSC) with and without subweig ht partition scheme. It is shown that the adaptive H-infinity algorithm wit h subweight approach has the advantages of fast convergence speed, insensit ivity of dynamic estimate error, and suitability for arbitrary ambient nois e over the conventional H-infinity and the RLS-based adaptive algorithms.
