1. A receiving apparatus comprising:
- a plurality of synchronizing circuits which is provided corresponding to different preamble signals of a reception signal and operates simultaneously at the time of receiving the preamble signals so as to output correlation values of synchronous signals;
a correlation value comparing section which compares the correlation values output from the plurality of synchronizing circuits; and
a synchronizing section which outputs a synchronism acquisition signal based on a comparison result from the correlation value comparing section.

Abstract
A receiving apparatus according to the present invention has a plurality of synchronizing circuits which is provided corresponding to different preamble signals of a reception signal and operate simultaneously at the time of receiving the preamble signals so as to output synchronous signals, a correlation value comparing section which compares correlation values of the synchronous signals output from the plurality of synchronizing circuits, and a synchronizing section which determines whether the received signal is for the subject apparatus based on a comparison result from the correlation value comparing section.
