WiBro Femtocell을 위한 동기 모듈 개발

For avoiding interference and supporting handover, Indoor WiBro (Mobile WiMAX) System needs a synchronized signal to GPS 1pps signal. There are many candidates for WiBro femtocell synchronization but they have some limited conditions for deploying femtocells. In this paper, we surveyed existing solutions for WiBro femtocell. we proposed and developed new synchronization method, which make up for limited conditions of existing solutions.
