PROBLEM TO BE SOLVED: To remarkably improve resistance to inter-symbol interference and to restore signals substantially without degrading transmission efficiency in an environment wherein incoming waves exceeding a normal guard interval section come in. SOLUTION: In the transmitter for transmitting transmission signals in which symbols each being the basic unit of a digital signal are multicarrier-modulated, a subcarrier where the symbols are arranged in first OFDM symbols having a first guard interval and a subcarrier where the symbols are arranged in second OFDM symbols having a second guard interval whose length is determined by the transmitter are dispersed among the plurality of subcarriers configuring the multicarrier at the same time.
