    Abstract: The present invention is related to a receiver having a plurality of antennas for receiving and performing hybrid timing and frequency offset on at least one signal that includes at least one synchronization channel (SCH) symbol having a plurality of time domain repetitive blocks. The receiver further includes an auto-correlation unit that outputs an auto-correlation result and the power of the received signal, a coarse timing detection unit that generates a coarse timing metric, a frequency offset estimation unit that generates a coarse frequency offset metric based on the coarse timing metric and the received signal, a frequency offset compensation unit that generates a compensated version of the received signal, and a fine tuning detection unit that generates a fine tuning detection metric based on a sample of the compensated version of the received signal that is cross-correlated with a primary synchronization channel (P-SCH) code sequence.
