Journals: Enhanced MDIR Receiver for Space-Time Dispersive Channels
J. Vidal Manzano, M. Cabrera Bean, A. Agustin de Dios and M. A. Lagunas


A particular property of the MDIR (Matched Desired Impulse Response) receiver is introduced in this communication, namely, the fact that full exploitation of the diversity is obtained with multiple beamformers when the channel is spatially and timely dispersive. This particularity makes the receiver specially suitable for mobile and underwater communications. The new structure provides better performance than conventional and weighted VRAKE receivers, and a diversity gain with no needs of additional RF equipment. The baseband hardware needed for this new receiver may be obtained through reconfigurability of the RAKE architectures available at the base station. The proposed receiver is tested through simulations assuming UTRA FDD mode.
