摘要： The disclosed embodiments relate to a method and apparatus for performing a pilot synchronization operation in a wireless communication system. The system may contain a plurality of sliding correlators (102, 106, 110, 114) that each receives a portion of a received correlation sequence and provides a partial correlation output. An absolute value block (118-124) may take the absolute value of each partial correlation output. Circuitry (126) may combine the absolute values of each of the partial correlation outputs to form a correlation output.

A first correlator (108) may correlate for a real part of a first characteristic of the received signal to produce a first real correlated signal. A second correlator (110) may correlate for an imaginary part of the first characteristic of the received signal to produce a first imaginary correlated signal. A third correlator (114) may correlate for a real part of a second characteristic of the received signal to produce a second real correlated signal. A fourth correlator (116) may correlate for an imaginary part of the second characteristic of the received signal to produce a second imaginary correlated signal.
