<p>PROBLEM TO BE SOLVED: To provide a data transmitting method which can be effectively utilized for an OFDM system and can transmit data with a multicarrier at a low cost and a receiver. SOLUTION: A transmitter forms modulation signals by encoding data to be transmitted from a binary number to signals, forms an OFDM symbol by modulating plural subcarriers having the modulation signals and transmits the OFDM symbol at a rate related to the sampling frequency of the transmitter, the receiver is provided with a unit 28 for determining an analytic window concerning the signals received from the transmitter from a clock signal at a frequency related to the sampling frequency of the receiver, a unit 22 for forming a sample block and a unit 23 for inferring the transmitted modulation signals by demodulating the subcarriers of the sample block under consideration, and the inference unit 23 is designed so as to correct a change in the position of the analytic window in respect to the transmitted signal.</p> |
