Construction and analysis of rate-compatible punctured concatenated zigzag codes

In this paper, new rate-compatible punctured concatenated zigzag (RCPCZ) codes are proposed and analyzed by using the density evolution technique. This analysis gives the design criteria for the rate-compatible puncturing patterns and accordingly good puncturing patterns for constructing RCPCZ codes are obtained. Since RCPCZ codes are linear-time encodable and show capacity-approaching performance, they can be a good candidate technology for the next-generation communication systems. As their applications, Type-II hybrid automatic repeat request (HARQ) using RCPCZ code is constructed, which gives higher throughput than Type-II HARQ using RCMCZ code
