Abstract

In this paper, we propose a fast and robust blind multiuser equalisation scheme for the time-division duplex (TDD) component of the universal mobile telecommunication system (UMTS). In addition to the training-based equalisation performed using the midamble, blind detection is introduced over data fields to ensure continuous adaptation and better tracking performance. The latter strategy is mainly based on the affine projection scheme and the concurrent adaptation of both the constant modulus and decision directed modes. In computer simulations the performance of the proposed adaptation strategy is assessed for various UMTS TDD time bursts.
