Abstract :
In this paper we study LDPC code design in block-fading (BF) channels. Our main purpose is to introduce a new Root Check (RC)-LDPC code design which obtains full diversity whilst delivering improved coding gain relative the other LDPC code designs. More specifically, we show that when our codes are combined with the check splitting method for the ARQ BF channels, we obtain the highest coding gain relative to conventional RC-LDPC codes.
