摘要
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 transmission and reception time stamp of radio waves between the mobile terminal targeted for estimation and fixed Wi-Fi receivers. However, it is known that the accuracy of radio reception time stamp in existing Wi-Fi receivers may be deteriorated due to the influence of multipath environment. Therefore, this paper proposes a system that corrects the accuracy of symbol timing synchronization processing that determines the reception time of radio wave in Wi-Fi system. This will improve the estimation accuracy of Wi-Fi indoor mobile position estimation.
