摘要： Difference between a received signal which is an OFDM modulated signal having a guard interval and a delayed signal acquired by delaying the received signal by time equivalent to a data interval is calculated, a reference signal of an FFT calculation window is generated based upon the acquired result of the calculation of the difference and a predetermined threshold and a boundary between symbols is detected. As a result, the boundary between symbols can be stably detected, compared with a method of detecting a boundary between symbols based upon the result of the correlation calculation of the guard interval and the demodulation of received data is also stably enabled in multipath phasing and ghost.
