Abstract
An orthogonal frequency division multiplexing (OFDM) receiver includes a n average power calculation unit and an output unit. The average power calculation unit calculates and outputs a first average power of a null symbol section of each transmitted frame output from an OFDM transmitter and calculates and outputs second average powers of sub-carriers that correspond to each null symbol section. The output unit compares the first average power and the second average powers, to perform a reciprocal transformation on difference values of the first average power and each of the second average powers based on results of the comparisons, and to store and output reciprocally transformed values as channel state information.
