摘要： PROBLEM TO BE SOLVED: To provide a symbol synchronization method capable of frame synchronization and able to maintain synchronization at a baud rate, even when I and Q signals are one symbol or more out of phase.SOLUTION: The I component and Q component signals received are subjected to timing synchronization (20) while they are allowed to be one symbol or more out of phase. Next, in a plurality of combinations of the I and Q signals shifted by one symbol each, correlation processing with a preset synchronization purpose code series is executed on each, and a combination where the correlation value is maximum is detected, with which timing is performed frame synchronization (22). Then, finally, a plurality of correlation values are measured at timing intervals of within one symbol, the series of measured correlation values is subjected to least square approximation with a preset correlation function, and timing assumed to be the maximum of correlation value is determined by interpolation to be the synchronization position, whereby timing synchronization is executed (24).
