CONVERGENCE OF AN OPTIMAL CHANNEL ESTIMATION ALGORITHM FOR INTERFERENCE DS-CDMA SYSTEMS IN TIME-VARYING CHANNELS WITH STRONG
J.S. Lehnert · 2000
An optimal algorithm for channel parameter estimation in direct-sequence spread-spectrum (DS-SS) systems with strong interference is examined in this paper. The algorithm is based on the maximum likelihood (ML) criterion and a modification of the extended Kalmanfilte,: The algorithm is shown with an asymptotic analysis to determine the actual channel parameters. A complete implementation of the algorithm is described, and its transient behavior is examined by computer simulations.
