Abstract

Synchronization can be achieved by computing the correlation of a received signal using a locally stored synchronization sequence. The segment giving the maximum correlation is taken as the location of the sequence. In this letter, we present an ideal synchronization circuit using a sequence pair with bipolar correlation. When a sequence pair is inputted, the circuit outputs double maximum correlation values that are equal in magnitude and opposite in polarity at the zero and middle shifts, by using the sidelobe cancellation effect between the two sequences. Such a circuit is particularly useful for synchronization, since it can be used to double-check the synchronization timing.
