Abstract :
In this paper the estimation of the uplink channel parameters required for coherent multiuser time-frequency RAKE receivers is considered. A blind method based on correlation matching is developed that can estimate the channel parameters for each user to within a complex scalar ambiguity. The performance of the proposed method is assessed through simulations and compared with another estimation method for single and multiuser scenarios.
