Abstract :
A new criterion for performance evaluation of space-time block codes, based on the progressive union bound (PUB) is proposed. The PUB is not analytically tractable, in general, but can be well approximated by a saddlepoint approximation. The improvements provided by this new approach are illustrated by comparison with other bounds. New code sets, offering improved performance at low SNR, can also be found via the new bounds.
