MULTI-CARRIER RADIO RECEPTION EQUIPMENT AND MULTI- CARRIER RADIO TRANSMISSION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To solve a problem that the constitution of equipment becomes complicated since the number of FFT circuits, which is equal to that of branches, are especially required when multiple antennas are used in a multi-carrier radio transmission system. SOLUTION: Multi-carrier radio transmission equipment is provided with plural antennas 1, 2 and 3, plural antenna controls 4, 5 and 6 allocated for each divided band constituted by dividing a transmission band, synthesis parts 7, 8 and 9, Fourier transformation parts 10, 11 and 12 and demodulation parts 13, 14 and 15, which are individually installed in accordance with the antenna control and an arrangement part 16 integrating output signals from the demodulation parts.
