Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a system that verifies and corrects the accuracy of symbol timing synchronization processing to determine reception time in Wi-Fi system.
Time-of-flight (ToF) -based Wi-Fi indoor mobile position estimation uses radio time-of-flight data between the mobile terminal targeted for position estimation and a fixed Wi-Fi receiver (anchor) Using. However, it is known that the accuracy of radio reception time data in existing Wi-Fi receivers may be deteriorated due to the influence of multipath environment.
Therefore, we consider a system that corrects the accuracy of symbol timing synchronization processing that determines the reception time of radio waves in the Wi-Fi system. This will improve the estimation accuracy of Wi-Fi indoor mobile position estimation.
