摘　　要：为了提升传输时延计算精度,提出基于信道接入技术的通信端到端传输时延计算方法。将通信端到端传输过程中产生的时延分为传输设备传输时产生的时延、线路时延以及数据帧长度时延三种,计算端到端传输总时延,获得整个通信信号时序序列计算方法;结合信道接入技术,引入随机时延计算模型,去除高斯噪声产生的负面影响,计算单组信号在时延序列上出现的概率等,实现基于信道接入技术的通信端到端传输时延计算。仿真结果表明,所提方法能够有效减少时传输时延计算误差,充分验证了所提计算方法的有效性以及实用性。In order to improve the calculation accuracy of transmission delay, a method to calculate the end-to-end transmission time delay based on channel access technology was presented. The time delay in the end-to-end transmission was divided into the time delay caused by transmission equipment, the line time delay and the time delay of data frame length. And then the total time delay of end-to-end transmission was calculated to get the method of calculating whole communication signal temporal sequence. Based on channel access technology, the random time delay calculation model was introduced and the negative effect of Gaussian noise was removed. Moreover, the probability of a single set of signals appearing on the time delay sequence was calculated. Finally, the end-to-end transmission time delay calculation based on channel access technology was achieved. Simulation results show that the proposed method can effectively reduce the calculation error of the transmission time delay, and the availability and the practicability of the proposed method are fully verified.
