Abstract:
An OFDM receiving device for settling a problem of complicated configuration is provided, in that the OFDM receiving device receives an OFDM signal where no smaller than one specific sub-carriers among plurality of sub-carriers are modulated by a known modulation signal sk(t), and includes a converting means for converting the received OFDM signal into the received signals for each sub-carrier, an extracting means for extracting the ingredient caused by a frequency drift and a phase noise based on received signal rk(t) of the specific sub-carrier and the known modulation signal sk(t), and a compensating means for H) compensating the received signal of the sub-carrier using the extracted ingredient.
