  Abstract

In this letter, we propose a distributed root protograph (DRP) design for block fading (BF) channels that starts from the conventional RP structure to support a higher code rate of 1/( − 1). Although the proposed codes do not achieve full diversity, they attain the maximum diversity for given code rate and show a slope of frame error rate (FER) approaching the channel outage probability.
