Abstract :
In the next-generation mobile communication systems for various high-speed data services, the error correcting codes are required to have rate-compatibility, low decoding complexity and good performance for various frame lengths. In this paper, new rate-compatible punctured concatenated zigzag (RCPCZ) codes are proposed and analyzed by using the density evolution. As their application, type-II HARQ using RCPCZ code is shown to have better throughput at short frame lengths than yype-II HARQ using turbo code.
