1. A wireless communications device comprising:

  • at least one virtual antenna;

    a space-time filter circuit for filtering a communications signal received by said at least one virtual antenna by jointly estimating space-time filter weights and at least one channel impulse response (CIR); and

    a matched filter circuit downstream from said space-time filter circuit and having a filter response that is provided by a channel impulse response estimation from said space-time filter circuit.
