提出了部分窗口多拒绝选择重传(ARQ)协议,有效的提高确认效率,提高系统吞吐率、减小链路时延和时延抖动,从而节省了宝贵的无线资源。模型分析及仿真结果表明,此协议很好地适应了无线链路大时延、高误码率的特点。
This article proposes a Partial Window Multiple Rejects Automatic Repeat Request (ARQ) protocol, effectively improve the frequency spectrum efficiency and system throughout, reduce link delay and delay jitter, saving precious wireless resource. Model analyzing and simulation results validate that this protocol greatly accommodate the character of large-delay, high bit error rate in wireless link.
