ABSTRACT:
A method and an apparatus are provided, the apparatus includes a correlator configured to correlate samples of a frame format signal with a reference signal; an adder block configured to sum the correlation results over a given time period; a comparator configured to compare the sum with a given reference value; a controller configured, if the sum exceeds the reference value, to make the decision that a frequency correction channel has been detected, store the position of the frequency correction channel in the frame format signal and cease the correlation process; and otherwise configured to control the correlation and comparison to continue until the time reserved for the correlation process ends, to retain the value in the adder block; and to control the apparatus to resume the above process when a new time reserved for the correlation process is due.
