A modified implementation of the MMSE receiver to be used in a UTRA TDD environment is presented. Simulations are carried out in a multipath fading environment and BER values are obtained, demonstrating that this structure reduces the MAI that appears due to the loss of orthogonality between orthogonal codes in multipath channels. The performance of the proposed structure is compared with that of a traditional receiver, an equaliser and a RAKE receiver.
