针对有突发性错误的卷积码混合ARQ系统,提出了一种估计最优子包数的有效方法以及自适应子包传输方案。在理论分析最优子包数的基础上,对卷积码系统采用自适应子包传输后的性能进行了仿真验证。仿真结果表明,在动态信道中,自适应子包传输方案可使系统根据不同信道条件,采用不同的最优子包数可达到最大的吞吐量。

For hybrid ARQ system with bursting errors, an effective method to estimate amounts of optimized sub - packet and an adaptive sub - packet transmission solution are proposed for high speed data communication. The simulation verification for adaptive sub - packet transmission solution＇s performance is given based on the theoretical analysis of optimized amounts of sub - packet. Simulation results show that the adaptive sub - packet transmission solution can effectively improve the system throughput to the best according to different channel state in dynamic channels.
