    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 device and a method for determining the arrival time of a UWB signal including at least one pulse modulated at a carrier frequency. The receiver includes a frequency translation stage for translating the UWB signal to a first intermediate frequency and a second intermediate frequency. In an integration stage, the signals translated to the first intermediate frequency and to the second intermediate frequency are integrated on a time window to give a first integration result and a second integration result respectively. The phase deviation is determined between the first and second integration results and from this phase deviation, the arrival time of the UWB signal is deduced.

    Abstract: A method and a device are described for generating a signal representing data. The method for generating a signal has a step of modulating a portion (1P, 2P) of the data using phase shift keying and spreading the modulated portion over the at least one frequency base band using at least one highly auto-correlated spread code sequence (1C, 2C) associated with the frequency base band. The method for further has a step of delaying, according to a delay determined using a remainder (1R, 2R) of the data (ID), the at least one spread code sequence (1C, 2C) by a time delay wherein the modulated portion (1MP, 2MP) is spread according the delayed spread code sequence (1DC, 2DC).
