  • Abstract
    In this paper, we present a polynomial H∞ channel estimator for DS-CDMA systems with time-varying multipath fading channels which suffer from the lack of accurate knowledge of model dynamics and statistics of system noises. The algorithm is based on the Krein space theory and requires one J-spectral factorization. Compared with standard H∞ filter, the proposed algorithm is of lower computational complexity. The simulation results show that the proposed H∞ estimator provides a robust estimation performance against all kinds of noises and the modelling errors
