DETERMINING DEVICE AND DETERMINING METHOD FOR DETERMINING WHETHER COMMUNICATION IS POSSIBLE

摘要

A determination apparatus for determining communication availability in an Orthogonal Frequency Division Multiplexing (OFDM) scheme communication system, the determination apparatus includes a reception unit configured to receive a wireless signal including an OFDM symbol in which a pilot signal is inserted at a constant interval in a frequency axis direction, an obtaining unit configured to obtain a discrete sample signal by sampling the wireless signal, a correlation value calculation unit configured to calculate a correlation value of the discrete sample signal for a time shift amount that is defined in advance according to the constant interval, and a determination unit configured to determine the communication availability in the communication system based on at least a result of determination whether the correlation value for the time shift amount has a peak or not.
