We construct signal constellations for differential transmission with multiple basestation antennas. The signals are derived using the theory of fixed-point- free groups and are especially suitable for mobile cellular applications because they do not require the handset to have more than one antenna or to know the time-varying propagation environment. Yet we achieve full transmitter diversity and excellent performance gains over a single-antenna system
