We present three joint adaptive mean squared error receiver structures for a time division duplex down-link scenario in which a single mobile station is allocated several code-multiplexed channels. The first structure is a bank of single channel MMSE receivers. The second is composed of an equaliser common to all the received channels and a bank of matched filters for despreading. The equaliser can be updated using a multiple-error filtered-X LMS algorithm. The final proposed structure features both an equaliser and a bank of MMSE receivers. The performance of the three architectures is tested and compared under multipath fading channel propagation conditions and BER values are provided.
