<p><P>PROBLEM TO BE SOLVED: To provide a communication system for reducing deterioration of synchronization detection characteristics due to a vector of a received signal varying with frequency. <P>SOLUTION: A synchronization signal generating section 41 preliminarily recognizes a synchronization signal to generate the synchronization signal, a synchronization signal dividing section 42 divides the synchronization signal generated by the synchronization signal generating section 41 into a plurality of divided synchronization signals in frequency domain, an individual correlation calculation section 43 calculates a correlation value between each of the divided synchronization signals divided by the synchronization signal dividing section 42 and the received signal. An in-phase converting section 46 converts the correlation value calculated by the individual correlation calculation calculating section 43 in phase mutually. A synthesizing section 47 synthesizes the correlation value converted by the in-phase converting section 46. A synchronization determining section 49 detects a timing of synchronizing the received signal based on the correlation value synthesized by the synthesizing section 47. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
