Abstract: A method of differential unitary space-time modulation is provided by encoding messages to transmit through multiple transmitting antenna into multiple trellis code in a communication system wherein the signals are transmitted between multiple transmitting antennas and at least one receive antenna. The performance provided is superior to that of the modulation of the prior art.
