摘要： Respective demodulated outputs from a plurality of branches 11a to 11d are fed to corresponding error correction units 13a to 13d and error-corrected. The error correction units 13a to 13d feed error signals to error determination units 14a to 14d. The error determination units 14a to 14d determine the error-incidence situations of the respective branches 11a to 11d and then output the determination results to a coefficient generation unit 15. Based on the results of determination by the error determination units 14a to 14d, the coefficient generation unit 15 obtains the synthesis coefficients for the respective branch outputs. The synthesis coefficients correspond to the error-incidence situations of the respective branch outputs and are appropriate values including no errors. By synthesizing the respective branch outputs by use of the synthesis coefficients, error-free data can be reproduced.

摘要： A demodulation circuit receives an OFDM transmit signal containing an information carrier, an additive-information transmission carrier, and a reception-synchronization pilot signal to convert these carriers and signal into frequency-axial data. The information carrier transmits information data. The additive-information transmission carrier and the reception-synchronization pilot signal have a lower multi-valued modulation degree than the information carrier. A differential detection circuit conducts detection processing by using a detection-subject symbol of a plurality of symbols indicated at a predetermined interval in the same frequency range and a symbol ahead that detection-subject symbol by a predetermined time in either one output of the additive-information transmission carrier and the reception-synchronization pilot signal output from the demodulation circuit. A first S/N ratio generating circuit generates an S/N ratio based on a detection output provided from the differential detection circuit. The S/N ratio indicates the reception quality of the OFDM transmit signal.

摘要： A transmission system is disclosed which permits the receiving end to demodulate multi-valued modulated symbols successfully under fading conditions and reduces the amount of transmitted reference data to improve data transmission efficiency. At the transmitting end, a multiplexing section, a modulating section, and a transmitting section are provided. In transmitting an OFDM transmission frame, null symbols and reference symbols are placed in the beginning portion of the frame and QPSK symbols are placed in an information symbol data region in the frame with equal spacings in time and frequency. At the receiving end, a receiving section, a demodulation section, an equalizing section, and a demultiplexing section are provided. An error detector detects amplitude and phase errors of each carrier from the reference symbols, and a variation detector detects variations in the amplitude and phase of a received signal from the QPSK symbols. The carrier amplitude and phase errors are corrected by a correction information producing section on the amplitude and phase variations of the received signal detected by the variation detector to produce correction information. The equalizing section equalizes the demodulated symbol data according to the correction information.

摘要： An OFDM synchronization demodulation circuit includes a recovery circuit, an orthogonal axis demodulation circuit, a first and second delay circuit, a correlation calculation circuit, a guard timing detection circuit, and an OFDM signal demodulation circuit. The receiving circuit receives an orthogonal modulated wave based on an orthogonal frequency division multiplex (OFDM) modulated signal having an available symbol period and a guard period, where the guard period of the orthogonal modulated wave is based on a part of the available symbol period. The orthogonal axes demodulation circuit demodulates an in-phase axis detection signal and an orthogonal axis detection signal for the OFDM modulated wave from the receiving circuit using orthogonal detection. The first delay circuit delays the in-phase axis detection signal by the available symbol period, and the second delay circuit delays the orthogonal axis detection signal by the available symbol period. The correlation calculation circuit calculates coefficients of the correlations of the in-phase axis detection signal and the orthogonal axis detection signal from the orthogonal demodulation circuit with the output of the first or the second delay circuits. The guard timing detection circuit detects a timing of the guard period in the demodulation outputs from the orthogonal demodulation circuit. The OFDM signal demodulation circuit demodulates the OFDM modulated signal by extracting the available symbol period signal only from the demodulated output of the orthogonal demodulation circuit using the timing signal.
