RF RECEIVER HAVING TIMMING OFFSET RECOVERY FUCTION AND TIMMING OFFSET RECOVERY METHOD USING THEREOF

摘要

the present invention is a signal that in the event of sampling timing offset slot in accordance with the determination of the location the movement to offset the timing It relates to a radio receiving apparatus for recovery, and the pre-processing unit for digitizing the received signal by sampling the analog, and the differential delay by the differential calculating unit for receiving the digitized signal for a predetermined amount of time from the pre-processing unit, differential from the differential operation part correlating the received signal with each of a plurality of PN code sequence is set in advance to store the correlation unit for sequentially outputting a correlation value, the correlation value from the correlation unit in sequence, and detecting the maximum value of detected correlation value is stored and a setting unit for shifting the slot by determining the maximum value of the position error between the reference position set in advance, to estimate the symbols of the PN code sequence corresponding to the maximum value of the shift is determined from the value of the slot to demodulate the received signal It includes a demodulation estimation.
