摘　　要：文章基于当前缺少无线端到端延时精确测试方法的现状,提出了面向发送端或者接收端的无线通信单向时延测试方案。针对内部时钟授时这一影响时延测试结果的关键因素,提出了时钟线性补偿策略,实现秒内线性补偿以及多源高频时钟校正策略,实现CPU高频时钟替代。按照测试方案基于四层结构开发了测试终端,在示范区完成了无线网络单向时延和抖动值的测试验证。Based on the current lack of accurate test methods for wireless end-to-end delay,this paper proposes a wireless communication one-way delay test scheme for the sender or receiver.Aiming at the internal clock timing,a key factor affecting the delay test results,a clock linear compensation strategy is proposed to achieve linear compensation within seconds and a multi-source high-frequency clock correction strategy to achieve CPU high-frequency clock replacement.According to the test scheme,the test terminal is developed based on the four-layer structure,and the test verification of one-way delay and jitter value of wireless network is completed in the demonstration area.
