中文摘要：
通信系统的可靠性仍有待提高,无线网络的丢包问题是网络应用研究中比较重要的问题。通过对通信信道建模,利用计算机进行信道仿真,可以不完全依靠实际的网络而进行相关网络应用的分析实验。基于马尔可夫Gap模型,提出了一种改进的网络丢包模型,并基于该模型进行了分析和仿真实验。该方法不仅考虑了长时间的网络丢包状况,同时考虑了相邻丢包之间的相互关系,能够比现有模型更加准确地描述3G网络的丢包特性。
英文摘要：
Since the reliability of the communication system remains to be improved, packet loss is still a crucial issue in wireless network application research. Analysis experiments for network applications can be performed by computer simulation based on the communication channel model, not entirely rely on the actual network. An improved network packet loss model based on Gap model is proposed, and the simulation method is also described after the analysis of this model.Without complex calculation, the model can characterize the packet loss situation for long time and the interrelation between adjacent packet losses. It can simulate the packet loss characteristic of 3G network more accurate than existing models.
