Abstract
Provided is a link synchronization method for a radio frequency repeater that can perform link route switching at an accurate time point by measuring reception signal power at a predetermined period for a predetermined time duration, accumulating and comparing them with a reference level, and detecting a link termination time point. The method includes: a) setting up an initial link route; b) measuring received signal power in the initial link route; c) accumulating the reception signal power received for a predetermined time at a predetermined period, when the reception signal power is detected; d) setting up a reference level for link switching based on the accumulated reception signal power; e) detecting a link termination time point by finding an edge in a waveform of the accumulated reception signal power based on the reference level; and f) switching the current link route based on the detected link termination time point.
