Abstract:
An incremental redundancy hybrid automatic repeat-request(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 decoding complexity and parallelism, make it more attractive in practice than the IR-HARQ schemes based on both turbo and LDPC codes.
基于非规则重复累加码(IRA)提出一种冗余递增自动重传协议(IR-HARQ)且该自动重传协议的性能取决于速率匹配删截IRA码的性能.在此基础上提出用线性规划结合一维概率密度演化算法解决核心的速率匹配删截IRA码的设计问题, 并给出了设计结果.仿真表明:相比于基于turbo码的相应方案, 所提方案的性能在短帧(帧长1 024)下大体相仿, 而在长帧(帧长4 096)下表现出一定的优势.相比于turbo和低密度校验码, 基于IRA码的方案在解码的复杂性以及并行化方面具有独到的优势.
