Abstract :
The usual approach to improve transmission performance over Rayleigh fading channels is to increase the system diversity. This usually entails an increase in power or bandwidth. The type of diversity we propose does not present these drawbacks. The diversity is embedded in the signal constellation and it directly depends on the Hamming distance between the constellation vectors. We also analyze additional coding schemes to apply to high modulation diversity constellations
