ABSTRACT:
Methods and system for frame synchronization for a mobile communication system is disclosed. A downlink synchronization signal is detected. Multiple sub-frames on the basis of the detected synchronization signal are stored. An optimum position of a midamble sequence is detected using a correlation in accordance with sub-frames. A phase sequence of sub-frames is calculated by using a correlation value at the optimum position of the midamble sequence and a maximum correlation value of a synchronization signal. A frame synchronization is obtained on the basis of a phase position of a sub-frame. The frame synchronization is periodically updated.
