1. A method for transmitting, with increased diversity in fading channels, an input signal from a plurality of transmit antennas, the method comprising:

  • jointly encoding, across at least two pipes, and modulating an input signal into a codeword, the codeword spanning a frame and defined as at least one complex symbol that describes all complex values to be transmitted during all channel uses covered by the frame, each complex symbol having a first and a second coordinate;

    after encoding and modulating, interleaving the coordinates within a transmission frame that corresponds to a predesignated number of channel uses by said encoder; and

    transmitting the frame of interleaved coordinates by L transmit antennas, wherein L is an integer greater than one.
