ACQUISITION OF TIMING INFORMATION IN WIRELESS COMMUNICATION SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide a method for identifying a reference point in time in a wireless communication system.SOLUTION: The method includes: receiving a first repeated sequence of symbols; receiving a second repeated sequence of symbols; performing autocorrelation between the first and second sequences of symbols; and identifying as the reference point in time an autocorrelation null between the first and second repeated sequences of symbols. An apparatus for identifying the reference point in time includes: means for receiving the first repeated sequence of symbols; means for receiving the second repeated sequence of symbols; means for performing autocorrelation between the first and second sequences of symbols; and means for identifying as the reference point in time the autocorrelation null between the first and second repeated sequences of symbols.
