Blind adaptive H~∞ multiuser detection for CDMA systems with impulsive noise

摘要

In this letter, blind adaptive H~∞multiuser de- dection is developed by employing a generalized sidelobe canceler (GSC)with and without subweight partition scheme. It is shown that the adaptive H~∞algorithm with subweight approach has the advantages of fast convergence speed, insensitivity of dynamic es- timate error, and suitability for arbitrary ambient noise over the conventional H~∞and the RLS-based adaptive algorithms.
