摘要： A modulation apparatus is disclosed that enables great improvements in signal transmission rate in a limited frequency band as compared with conventional modulation schemes. Modulation apparatus 100 has first and second frequency-increasing SSB modulators 110 and 120. The modulators 110 and 120 are configured to have respective carrier frequencies with a difference by a frequency corresponding to the reciprocal of the symbol rate (i.e. fundamental frequency of the input symbol). Adder 130 combines a LSB signal obtained from the SSB modulator 120 set for a higher carrier frequency, and a USB signal obtained from the SSB modulator 110 set for a lower carrier frequency to obtain a modulation signal.

摘要： A modulation apparatus is disclosed that enables significant improvements in signal transmission rate in a limited frequency band as compared with conventional modulation schemes. The modulation apparatus has first and second frequency-increasing single side band (SSB) modulators. The modulators are configured to have respective carrier frequencies with a difference by a frequency corresponding to the symbol frequency (i.e. fundamental frequency of the input symbol). An adder combines a lower side band (LSB) signal obtained from the SSB modulator set for a higher carrier frequency, and an upper side band (USB) signal obtained from the SSB modulator set for a lower carrier frequency to obtain a modulation signal.

摘要： A modulating device capable of generating an OFDM signal and having a drastically improved frequency use efficiency. The modulating device has modulators (6, 8 (11, 13, 106, 108, 111, 113)) for modulating a signal to be modulated and having a Nyquist roll-off frequency characteristic with a carrier frequency having a difference two times the Nyquist frequency and combiners (10(15, 110, 115)) for generating modulation output having a speed two times that of the signal to demodulated and the same Nyquist roll-off slope as the signal to be modulated by combining the outputs of the modulators (6, 8 (11, 13, 106, 108, 111, 113)). Thus a double speed wave can be superposed on the same frequency without varying the roll-off slope of the Nyquist characteristic, and therefore an OFDM signal (19) having a drastically improved frequency use efficiency is provided.

摘要： A transmission weight computing section computes a transmission weight for directional transmission using an OFDM signal. A transmission correcting value memory section stores one correcting value for correcting the transmission weight for each sub-carrier of an OFDM signal or each band gathering a plurality of sub-carriers. A transmission weight correcting section corrects the transmission weight by the correcting value. A transmitting branch weights transmission data by a transmission weight outputted from the transmission weight correcting section on a sub-carrier-by-sub-carrier basis and delivers it to an antenna.
