Abstract:
The present invention relates to a method of estimating symbol synchronization for an Offset Quadrature Phase Shift Keying (OQPSK) demodulator applicable to a Zigbee receiver. More particularly, the invention relates to a method of recovering symbol synchronization of an OQPSK demodulator in which a reference correlation value is reset using a correlation value of a reception signal when detecting symbol synchronization in the OQPSK demodulator, preventing errors in detecting symbol synchronization due to noise, thereby increasing the accuracy in symbol synchronization.
