摘要： Equipped with a plurality of mapping blocks 102 and 103 that carry out mappings of different rates, signals subjected to low-speed mapping are placed in the periphery of a band to which a plurality of sub-carriers are assigned at an interval corresponding to the symbol rate. The signal placed on the frequency axis in this way is converted to a time waveform through inverse Fourier transformation block 105, converted to a symbol time series through parallel/serial conversion block 106, then quadrature-modulated and transmitted.

摘要： Slot quality detector 121 detects reception level, and power controller inversely corresponding to reception quality 122 outputs power control information indicative of increasing transmission power in the case where the detected reception level is higher than a threshold value and of decreasing the transmission power in the case where the detected quality is lower than the threshold value. Transmission power setter 108 performs the setting of transmission power corresponding to the power control information and provides a control to transmit by the set power. That allows improving of a battery saving and moderating of the specification of amplifiers in a transmission/reception apparatus, thereby resulting in decreased interference to signals of other users in the CDMA communication.

摘要： A differential detector imparted with error correcting function for detecting a differentially phase shifted signal while performing error correction includes a one-symbol differential detector for performing phase comparison between a current input signal and a signal preceding by one symbol, a delay circuit for delaying a one-symbol differential detection signal by two symbol periods, a two-symbol differential detector for performing phase comparison between the current input signal and an input signal preceding by two symbol periods, a four-symbol differential detector for performing phase comparison between the current input signal and an input signal preceding by four symbol periods, and two error correction circuits. By making use of the four-symbol differential detection signal, error correction of the two-symbol differential detection signal is performed by the error correction circuit while error correction of the one-symbol differential detection signal is performed by using the corrected two-symbol differential detection signal. By diminishing the error of the two-symbol differential detection signal, the error correcting capability for the one-symbol differential detection signal is enhanced with bit error rate characteristic being improved.

摘要： A data receiving system has a radio frequency unit for demodulating a series of signals transmitted at a carrier wave frequency, a local oscillating unit for generating a demodulating frequency used for the demodulation of the series of signals, an equalizing unit for removing a distortion of the series of signals demodulated in the radio frequency unit, a phase shift estimating unit for taking out phase information from the series of signals, calculating a time changing rate of the phase information and estimating a phase shift caused by a difference between the carrier wave frequency and the demodulating frequency according to the time changing rate, and a correcting unit for correcting the series of signals transmitted from the equalizing unit according to the phase shift to remove the phase shift from the series of signals. Accordingly, because the phase shift is estimated by using the phase information placed in the series of signals, an influence of a bit pattern of a series of training bits arranged in the series of signals can be removed.

摘要： A data signal composed of a desired signal faded and delayed and an interference signal faded and delayed is received by a pair of antennas. A direct component of the interference signal and a delay component of the desired signal are removed from the data signals received by the antennas in a decision-feedback type of desired signal equalizing unit, and the direct component of the desired signal and the delay component of the interference signal are removed from the data signals in a decision-feedback type of interference signal equalizing unit. Also, a delay component of the interference signal is removed in the desired signal equalizing unit by subtracting a replica of the delay component of the interference signal produced in a backward tap from a demodulated interference signal produced in the interference signal equalizing unit in a previous operation, and a delay component of the desired signal is removed in the interference signal equalizing unit by subtracting a replica of the delay component of the desired signal produced in another backward tap from a demodulated desired signal produced in the desired signal equalizing unit in the previous operation. Therefore, the demodulated desired signal agreeing with the desired signal is output from the desired signal equalizing unit, and the demodulated interference signal agreeing with the interference signal is output from the interference signal equalizing unit.

摘要： A data receiving apparatus includes: a receiving portion for receiving a QPSK (PSK, GMSK) signal using a local oscillation signal; a forward (FWD) equalizing portion for effecting a FWD equalization to the PSK signal using FWD tap coefficients, including a FWD main tap coefficient, successively renewed; a backward equalizing portion for effecting a backward equalization to the PSK signal using backward tap coefficients, including a backward main tap coefficient, successively renewed; and a prediction portion for predicting a phase difference between a carrier frequency of the PSK signal and the local oscillation frequency according to the FWD and backward main tap coefficients. In this apparatus, the FWD and backward equalizing portions effect FWD and backward equalizing training processings using the sync word in the PSK signal in the FWD and backward directions to determine the FWD and backward tap coefficients before FWD and backward equalizations respectively. It may further include a correction portion for compensating a phase difference in outputs of the FWD and backward equalizing portions according to the predicted phase difference. The local oscillation frequency is controlled according to the predicted phase difference.
