Abstract :
We consider FEC coded transmit diversity with space-time block codes. We show that all space-time block codes are equivalent in terms of SNR per bit and give a new view on space-time block codes as a transformation of the fading MIMO channel towards a Gaussian SISO channel. Using a simple equivalent channel model we provide analytical results on the BER of uncoded and FEC coded transmit diversity. Finally, we roughly discuss using multiple antennas for transmit diversity or beamforming
