Abstract
A modulator, and an associated method, are described for use by a sending station, operable in a communication system, to communicate data to a receiving station upon a communication channel susceptible to fading. The modulator includes a mapper for mapping modulator output symbols to a set of antennas. The modulator ensures that an Orthogonality Condition is satisfied to impart maximum transmission diversity upon the data sent over the fading communication channel.
