Abstract :
This paper introduces some simple mapping constraints on differential space-time block codes such that the transmission constellation is not expanded. Connections between these schemes and differential space-time modulation are discussed. Simulation results show that these schemes provide full spatial diversity and trade-off between data rate and performance.
