METHOD FOR RECEIVING MULTICARRIER SIGNAL AND MULTICARRIER RECEIVER COMPRISING IT

摘要

A multicarrier receiver which dispenses with a guard interval and avoids an influence of an intersymblol interference (ISI) based on the height of the guard interval. This multicarrier receiver has a serial/parallel converter for receiving a multicarrier signal to convert it into a parallel signal, a Fourier transformer for selecting a multicarrier signal over a section longer than one symbol of the received multicarrier signal from an output of the serial/parallel converter to subject the selected multicarrier 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 multicarrier 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.
