Concatenated space-time block coding with maximum diversity gain

In this work, we propose a concatenated space-time block coding scheme for transmissions of over block fading frequency selective channels, which guarantees maximum diversity gain and high coding gain, with affordable receiver complexity. We derive a closed form expression for the bound of the pairwise error probability, which is instrumental to devise the optimal coding strategy, and then we check out theoretical derivations with simulations and compare our approach with alternative ones.
