A multi-carrier receiver which dispenses with a guard interval and avoids an influence of an intersymbol interference (ISI) based on the height of the guard interval. This multi-carrier receiver has a serial/parallel converter for receiving a multi-carrier signal to convert it into a parallel signal, a Fourier transformer for selecting a multi-carrier signal over a section longer than one symbol of the received multi-carrier signal from an output of the serial/parallel converter to subject the selected multi-carrier signal to discrete Fourier transform, a channel compensator for subjecting the Fourier transform signal to channel equalization, a matrix conveter for contracting the dimension of the signal of channel equalized signal down to the dimension of the received multi-carrier signal, a parallel/serial converter for converting the output of the matrix converter into a serial signal, and a demodulator for matching the output of the parallel/serial converter with the modulator on a transmitter side, and a decoder for matching it with an encoder.
