RELAY DEVICE AND BROADCAST SYSTEM WITH USE OF THE SAME

Title:

RELAY DEVICE AND BROADCAST SYSTEM WITH USE OF THE SAME

Document Type and Number:

WIPO Patent Application WO/2008/056439

Kind Code:

A1

Abstract:

A receiving filter (12) and a receiving amplifier (14) receive an OFDM signal that channels are multiplexed in frequency. An FFT unit (70) carries out Fourier transform processing for the received OFDM in a lump so as to generate a plurality of sub-carrier signals. A changing unit (72) changes dispositions of the generated sub-carrier signals while packaging sub-carrier signals included in one channel. An IFFT unit (74) carries out inverse Fourier transform processing for a plurality of the changed sub-carrier signals so as to generate a new OFDM signal. A transmitting amplifier (24) and a transmitting filter (26) transmits the newly generated OFDM signal.
