In this correspondence, a tight lower hound to the outage probability of discrete-input Nakagami-m block-fading channels is proposed. The approach permits an efficient method for numerical evaluation of the bound, providing an additional tool for system design. The optimal rate-diversity tradeoff for the Nakagami-m, block-fading channel is also derived and a tight upper bound is obtained for the optimal coding gain constant.
