dc.description.abstractIn downlink transmission, channel multipaths destroy the orthogonality between users causing Multiple Access Interference (MAI). In order to restore the orthogonality between the users, chip-level channel equalization based on the iterative conjugate-gradient (CG) algorithm has been proposed in [Heikkilla '02]. We extend this approach to the multiple transmit antenna case and propose 16-bit fixed point implementation. Simulations show the robustness of the fixed point implementation of the proposed algorithm. Moreover, this approach outperforms RAKE receiver in all cases.en_US
