1. A communication method determination apparatus comprising:
a processor; and
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
obtain a bit string of a portion of a physical header for synchronization from a wireless frame that includes the physical header for synchronization in which information for synchronization in a physical layer is set and a physical data portion in which data of a higher-level layer than the physical layer is set, and compare the obtained bit string with a bit string pattern specific to a communication method targeted for determination; and
perform communication method determination processing for determining whether or not the communication method targeted for determination is used for the wireless frame, based on a result of comparison performed by the comparison unit, and if it is determined in the communication method determination processing that the communication method targeted for determination is not used for the wireless frame, change the communication method targeted for determination to another communication method, instruct the comparison unit to newly obtain a bit string of a portion that follows the obtained bit string, from the physical header for synchronization of the wireless frame, and to compare the newly obtained bit string with a bit string pattern specific to the post-change communication method targeted for determination, and perform the communication method determination processing again.
