文章针对远距离点对点无线通信的特点 ,在标准全双工选择式ARQ滑动窗口协议的基础上 ,引进了多种自适应措施 ,包括可变的回传确认定时、重发计次措施以及自适应多次确认。对协议性能的理论分析和实验测试表明 ,协议在长RTT延时和强干扰的通信条件下能够实现高效可靠的数据传输 Aiming at the characteristics of long-distance point-to-point wireless communication, this paper introduces a variety of adaptive measures based on the standard full duplex selective ARQ sliding window protocol, including variable acknowledgment timing, retransmission secondary measurement and adaptive Confirm multiple times. The theoretical analysis and experimental tests on the performance of the protocol show that the protocol can achieve efficient and reliable data transmission under the conditions of long RTT delay and strong interference
