摘要： Influence from an adjacent signal is prevented even if a guard band is not provided.A phase comparison unit 21 compares a reference window signal input to a PLL circuit 4 and a window signal supplied from a frequency division circuit 22 and outputs the comparison result to an LPF 23. The LPF 23 extracts a low frequency component from the input signal and outputs the same to a voltage controlled oscillator 24. The signal output from the voltage controlled oscillator 24 is supplied as a clock to units of an OFDM modulation circuit 2 and, at the same time, supplied to the frequency division circuit 22. The frequency division circuit 22 divides the frequency of the supplied signal to thereby generate a new window signal and supplies the same to an IFFT unit 13. Further, the generated window signal is supplied to a PLL circuit 5. The PLL circuit 5 generates a clock for controlling a frequency modulation circuit 3 based on the supplied window signal.

摘要： The time required for switch the channel can be remarkably curtailed. When broadcasting signals through a plurality of information channels with an OFDM system, the plurality of information channels are multiplexed in the sense of frequency and collectively subjected to IFFT modulation for connected transmission instead of subjecting the plurality of information channels independently to OFDM modulation for transmission. With this arrangement, the efficiency of exploitation of frequencies is improved. According to the invention, the OFDM frames are synchronized for each information channel for the purpose of connected transmission. Then, the OFDM receiver can switch the information channel for signal reception, maintaining the frame synchronizing signals.

摘要： An apparatus and method for receiving an OFDM signal arranged to accurately reproduce a clock signal. I channel data and Q channel data are differential-demodulated by a differential demodulation circuit and are supplied to a ROM. The ROM reads out an intersymbol phase change amount corresponding to the differential-demodulated data and supplies it to a gate circuit. The gate circuit extracts only a component corresponding to each of pilot signals in the input data, and supplies the extracted component to a sign inversion circuit and to a selector. The selector selects the output from the gate circuit if the pilot signal is a positive frequency value or the output from the sign inversion circuit if the pilot signal is a negative frequency value, and supplies the obtained value to a cumulative addition circuit. The cumulative addition circuit performs cumulative addition of values output from the selector over a symbol period, and outputs the addition result to an average circuit. The average circuit averages the output from the cumulative addition circuit and controls the frequency of oscillation of a clock signal according to a value obtained by the average circuit.
