Fading-resistant transmission using built-in time diversity and several antennas

Transmission over mobile fading channels requires some diversity scheme to obtain better error rates. The objective of this paper is to present systems that combine coded modulation with built-in time diversity, an optimized constellation and multiple transmission antennas. The transmission systems are simulated over fast-fading channels that present Doppler effects. A gain of 12 dB is attained in comparison with other proposed systems.
