Header information identification device and header information identifying method

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of reducing an operation amount necessary for header information detection.;SOLUTION: A header information identification device includes a storage unit which stores a signal replica per pattern of header information of a received signal and identifies header information of the received signal without decrypting the received signal. This device calculates cross-correlation values between the received signal and signal replicas, and estimates the header information of the received signal on the basis of a signal replica having a high cross-correlation value.;COPYRIGHT: (C)2013,JPO&INPIT
