Orthogonal Frequency Division Multiplexing (OFDM) is combined with a plurality of transmitting antennas to yield a system that provides space, frequency and time diversity. Specifically, an arrangement is created where a transmitter includes a plurality of antennas that are transmitting simultaneously over the same frequency subbands, and the symbols that are transmitted over each subband, in any given time slot, over the different antennas are encoded by employing negations and complex conjugations (NCC) to provide diversity. The principles of NCC space-time coding, or any other NCC-type diversity-producing coding can be applied in this arrangement.
