US Patent 11350297 Radio frame analysis system, radio frame analysis method, and program

An appropriate time is set as an acquisition period during which a reception data sequence for extracting a frame feature value is acquired. A radio frame analysis system includes a transmission node number count unit that counts the number of transmission nodes from a reception data sequence, an acquisition period calculation unit that calculates an acquisition period based on a result of the counting by the transmission node number count unit, and a frame feature value extraction unit that extracts a frame feature value of each of the transmission nodes from the reception data sequence received in the acquisition period.
