Slow-fading channel, also known as block-fading (BF) channel, is a type of realistic and simple channel model that can capture the fundamental characteristics of a number of wireless-communication applications with low to moderate mobility. Although the BF channel has received significant research attention in the past two decades, designing low-complexity outage-limit-approaching error-correction codes (ECCs) is still a challenging problem. For this reason, we have proposed a new family of structured low-density parity-check (LDPC) codes, called root-protograph (RP) LDPC codes, recently. The RP codes can not only realize linear encoding and fast decoding with the help of a quasi-cyclic (QC) structure, but also achieve near-outage-limit performance in a variety of BF scenarios. In this talk, we will introduce the design guidelines of such type of protograph codes.
