Abstract

Mobile WiMAX Femtocell Access Point can acquire synchronization from the clock master with IEEE 1588 algorithm to deliver timing information over Ethernet. Thus, to keep a high degree of accuracy and precision, reciprocity of up/down links needs to be guaranteed. However, up/down links speed is not same in every case and it thus degrades performance. Thus, we analyze the impact of synchronization deterioration.

移动WiMAX Femtocell同步问题
移动WiMAX Femtocell接入点采用IEEE 1588算法从时钟主站获取同步信息,通过以太网传递定时信息。因此,为了保持高度的准确性和精度,需要保证上下链路的互易性。但是,上行/下行链路速度在每种情况下都不相同,因此会降低性能。因此,我们分析了同步退化的影响。
