摘要： The invention relates to methods for synchronising a device to a signal containing a train of pulses representing a programmable number of repetitions of a predetermined code. Pulse position and code phase are searched for. In a first aspect, a programmable number of samples is taken per pulse frame in function of the available number of repetitions of said predetermined code. In a second aspect, the method comprises a signal detection stage from which, after performing a confirmation stage, information can be kept for a subsequent stage. In a third aspect, only a limited number of rotated versions of the predetermined code are checked, using a presumed code phase which is kept from a preceding stage.

摘要： The present invention relates to a wireless communications system, in particular to a method for transmitting and receiving concatenated data bursts in a wireless communications system. The invention is particularly useful in the field of impulse-based ultra-wideband systems. In an aspect of the invention, a transmitting device is presented for generating and transmitting concatenated bursts or string. In another aspect of the invention, a receiving device is presented for receiving the string. The receiving device further uses frequency domain equalization approach to mitigate inter-symbol interference within the string.
