Abstract:
1. Receiver for receiving frequency signals, the receiver comprising: a processing stage for converting the frequency signals into baseband signals comprising preamble symbols and data symbols and for processing the baseband signals; and a synchronization stage for synchronising the processing stage and comprising a first part for performing a coarse time synchronization and a second part for performing a fine time synchronization, wherein the first part comprises an autocorrelating unit for autocorrelating samples of a group of preamble symbols, wherein the second part comprises a crosscorrelating unit for crosscorrelating samples of a further group of preamble symbols with predefined samples, and wherein the result of the autocorrelating the samples of the group of preamble symbols by the autocorrelating unit is not used by the crosscorrelating unit for the crosscorrelating the samples of the further group of preamble symbols with the predefined samples.
