The present invention relates to ultra wide band (UWB) applications such as radar, position tracking and communications for example Ground Penetrating Radar (GPR) and Wireless Personal Area Networking (WPANs). The present invention provides an apparatus for synchronising a receiver to a received UWB signal having a known hopping code, the apparatus comprising: means for determining a parameter of the signal in a number of time slots; means for adding the parameter associated with each time slot to a number of corresponding of time and code offset accumulators; means for determining the code and time offset accumulator having an accumulated value according to a predetermined accumulator metric as the code and time offset required to synchronise the receiver. <IMAGE> |
