Wireless communication system, wireless communication device and valid path detection method therefor

摘要

A wireless communication system according to an exemplary aspect of the present invention is a wireless communication system which performs wireless communications between a first wireless communication device and a second wireless communication device, wherein the first wireless communication device includes: a delay profile calculation unit for calculating a delay profile by calculating a correlation value for a received signal; a valid path detection unit for detecting a valid path using the delay profile and forcibly detecting a valid path when there is no path satisfying a condition of the valid path; and a forcible valid path notification unit for notifying that the valid path is forcibly detected.
