<P>PROBLEM TO BE SOLVED: To provide a method for detecting frame synchronization, in which a resistivity to a frequency drift of a receiving signal is enhanced and a possibility of detecting a synchronous word normally is enhanced, thereby enhancing a possibility of detecting a symbol timing normally. <P>SOLUTION: This method for detecting frame synchronization contains a phase shift process of generating L sample signal groups in which each phase of the sample signal groups is shifted by π/2L (L: a positive integer of 2 or more), and a determination process and detection process are performed for each of the thus-generated L sample signal groups to detect the synchronous word and symbol timing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
