单频网同步系统原理分析与设计

In this paper, radio frequency synchronization technology (RFST) which can achieve synchronization in the single frequency network is proposed by analysis the Single Frequency Network Synchronization System. The technology uses radio waves for broadcasting the modulated signal to transmit copies of the way the spectrum to all radio base stations by optical fiber, microwave, and satellite transmission medium, each base station digitize synchronous storage and processing RF signal, pre-distortion linear processing RF signal and so on. The technology achieves better consistency of the spectrum and time delay and providing a new engineering solutions to achieve excellent signal coverage of the single-frequency networking .
