Abstract :
In this paper, we present a new design of constructing full diversity unitary constellations using differential space-time modulation for any number of transmitter and receiver antennas. These constellations are constructed from a Bruhat decomposition which allows us to choose disjoint nonoverlapping cosets of a unitary diagonal subgroup in such a way that full diversity is preserved. Simulations show that our Bruhat constellations perform well in unknown Rayleigh fading channel.
