A Parallelized Synchronization Method for Wideband Wireless Systems

Acquiring initial synchronization with auto-correlation is simple and reliable method in wireless OFDM systems. However, recent trend of making use of wide-band frequency resources and accompanying high-frequency feature makes their implementation problematic. In order to solve this difficulty in developing our wireless backhaul system, we partitioned input signal into a few slower operation paths. This paper suggests how to acquire initial synchronization in this environment with minimum hardware and achieving performance goal in desired channel environment.
