一种TDD LTE-A与WiMAX-A垂直切换方案的研究

摘要

首先介绍了TDD LTE-A和WiMAX-A的研究背景，同时对垂直切换的原理进行了分析。在此基础之上，提出了一种基于 TDD LTE-A 与WiMAX-A实际特点的切换方案，给出了二者相互切换的流程，并利用Matlab仿真。最后，结合仿真结果论证了所提方案在一定程度上降低了垂直切换中“乒乓效应”的结论。%　　This article introduces related research background of TDD LTE-A and WiMAX-A, mean-while, it analyzes thetheory about vertical handoff. Based on actual characteristic of these two heteroge-nous networks,it puts forward a strategy for vertical handoff, and designs aprocess for switching between LTE-A and WiMAX-A.At last, Matlabsimulation re-sults shows that this hand off scheme can reduce the"ping-pong effect"effectively.
