Design of rate compatible punctured IRA codes for IR-HARQ schemes
摘要
Abstract
An incremental redundancy hybrid automatic repeatrequest (IR-HARQ)scheme based on irregular repeat-accumulate (IRA) codes is proposed. The design of rate compatible punctured IRA codes suitable for an IR-HARQ scheme is well formulated and efficiently solved by a linear-programming method, along with a one-dimensional approach for density evolution. Compared to IR-HARQ schemes based on turbo codes, simulation shows that the proposed IR-HARQ schemes based on IRA codes may achieve almost the same performance at a block size of 1 024, but better throughput at a block size of 4 096. The advantages of the proposed scheme in implementation, including decodingcomplexity and parallelism, make it more attractive in practicethan the IR-HARQ schemes based on both turbo and LDPCcodes.关键词
