    Abstract: A data processor selects a set of BOC correlations in accordance with a BOC correlation function for the sampling period if the primary amplitude exceeds or equals the secondary amplitude for the sampling period. The data processor selects a set of QBOC correlations in accordance with a QBOC correlation function for the sampling period if the secondary amplitude exceeds the primary amplitude for the sampling period. The data processor uses either the BOC correlation function or the QBOC correlation function, whichever with greater amplitude, at each sampling period for carrier tracking. Further, the data processor, through combining two sets of BOC correlations with different chip spacings provides an alternative unambiguous code acquisition of the received signal.

    Abstract: A wireless terminal is operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station and includes clock circuitry, a wireless interface, and a Primary Synchronization (PSYNC) module. The clock circuitry generates a wireless terminal clock using a wireless terminal oscillator. The wireless interface receives the WCDMA signal, which is produced by the base station using a base station clock that is produced using a base station oscillator that is more accurate than the wireless terminal oscillator. The PSYNC module includes a plurality of PSYNC correlation branches. Each PSYNC correlation branch phase rotates the WCDMA signal based upon a respective frequency offset, correlates the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions, and produces PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions.

    Abstract: A transmitting apparatus includes a first OFDM modulator that generates a first OFDM modulation signal by modulating a first information signal using a first modulation scheme, the first OFDM modulation signal having a plurality of subcarriers. A second OFDM modulator generates a second OFDM modulation signal by modulating a second information signal using the first modulation scheme, the second OFDM modulation signal having a plurality of subcarriers, and that generates a third OFDM modulation signal by changing a second position in an in-phase quadrature-phase plane in which a signal point of the second OFDM modulation signal is positioned, to a third position, the third position being different from a first position in the in-phase quadrature-phase plane in which a signal point of the first OFDM modulation signal is positioned. A multiplexer generates a multiplexed signal to be transmitted in a common frequency band, by multiplexing the first OFDM modulation signal and the third modulation signal. A transmitter transmits the multiplexed signal.
