A transmitter includes an OFDM symbol generator for generating an effective symbol including a plurality of sub-carriers orthogonal to each other in frequency and sequentially generating an OFDM symbol in which a signal in a first period from a first end of the effective symbol is added to a second end of the effective symbol as a guard interval, and a convolution filter for performing an convolution operation on data strings at a plurality of sampling points of the OFDM symbol, wherein when the convolution filter performs a convolution operation on the first data strings including a data string at the first end of the effective symbol, the convolution filter performs the convolution operation on the first data strings in which a data string at the second end of the effective symbol is cyclically added to a data string at the first end.
