    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 translation: 如果主振幅超过或等于采样周期的次级振幅，则数据处理器根据采样周期的BOC相关函数来选择一组BOC相关。 如果次级振幅超过采样周期的主振幅，则数据处理器根据采样周期的QBOC相关函数来选择一组QBOC相关。 在每个采样周期，数据处理器使用BOC相关函数或QBOC相关函数（以较大振幅为准），用于载波跟踪。 此外，数据处理器通过组合具有不同芯片间隔的两组BOC相关性来提供接收信号的替代性明确代码获取。

    Abstract: A data processor (192) 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 (192) 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 (192) uses either the BOC correlation function or the QBOC correlation function, whichever with greater amplitude, at each sampling period to provide an aggregate correlation function that supports unambiguous code acquisition of the received signal.

    Abstract: A system and method include a modulator to combine satellite codes with a carrier signal on an I-Channel and a Q-Channel. A processor applies a code power fraction to the combined codes on the I-Channel and the Q-Channel to provide a unity amplitude while maintaining a phase angle so that a signal constant envelope transmission can occur without a balancing code.

    Abstract: A method of embedding information within a burst carrier signal, the method comprising modulating meta-data using a modulator such that a meta-carrier signal results, lowering a Power Spectral Density (PSD) of the meta-carrier signal by Direct Sequence Spread Spectrum (DSSS) chipping the meta-carrier signal using a linear Pseudo-Random Number (PRN) sequence, embedding one or more modulated symbols of the meta-carrier signal within an unused portion of one or more quadrants of a modulation constellation of a burst carrier signal such that a composite carrier signal results, and synchronously transmitting the composite carrier signal using a transmitter such that symbols of the meta-carrier signal are synchronized with symbols of the burst carrier signal.

    Abstract: L'invention concerne un récepteur UWB à correction de dérive temporelle. Après translation de fréquence par un démodulateur en quadrature (240), le signal impulsionnel UWB reçu est intégré sur des fenêtres temporelles successives (260), puis échantillonné (270). Un estimateur de déphasage (280) détermine la différence de phase entre des échantillons séparés par un multiple de la période d'échantillonnage approchant la période des impulsions du signal. Des moyens de contrôle (290) déduisent de cette différence de phase un décalage temporel à appliquer aux intégrateurs (260) pour synchroniser le récepteur sur le signal reçu.

    Abstract translation: 本发明涉及具有时间漂移校正的UWB接收机。 通过正交解调器（240）进行的频率转换之后，所接收的UWB脉冲信号在连续的时间窗口（260）上被积分并且随后被采样（270）。 相移估计器（280）确定由接近信号脉冲周期的采样周期的倍数分开的采样之间的相位差。 基于相位差，控制装置（290）推导出要对积分器（260）施加的时移，以便使接收机相对于接收信号同步。
