Patent ID: 8447005

Claim:
A method in a receiver of determining a timing and a frequency offset of a received signal, the signal being predetermined, comprising: a. correlating, in the receiver, the received signal to each of a plurality of local replicas of a first predetermined signal, wherein the local replicas correspond to respective, different frequency offsets f i , i=1, 2, . . . , N, in a frequency offset range [f a , f b ], thereby forming a plurality of first correlation results; b. determining a maximal peak f max and a timing t max of the maximal peak f max in the plurality of first correlation results; c. determining at least one frequency offset f j based on the maximal peak f max and at least one other timing t j based on t max , wherein f j and t j are also based on characteristics of the first predetermined signal and are independent of a frequency offset of the maximal peak f max ; d. correlating, in the receiver, the received signal at (t max , f max ) and (t j , f j ) to a second predetermined signal, thereby forming at least two second correlation results; and e. determining the maximum of the at least two second correlation results, thereby determining the timing and the frequency offset.
