Recently, the Long Term Evolution (LTE) standard has been developed in the 3rd Generation Partnership Project
(3GPP) as the future wireless communication system. Cell search is a basic procedure of any cellular communication
system by which a mobile terminal finds a cell for potential connection to, and then decodes all the information required
to register. This paper presents a review of the state of the art solutions and recent patents in the fields of cell search and
synchronization for LTE and wireless systems. Moreover, a recently introduced innovative acquisition technique is illustrated
and depicted in details. Performance analysis is conducted in comparison with the conventional state of the art solution,
evaluating the probability of detection under different multi-path standard channels.
Keywords: Code acquisition, LTE systems, synchronization, spread-spectrum communications, wireless communications.
