Abstract:

A method is proposed to fast acquire primary synchronization signal (PSS) for cell edge users in
long term evolution (LTE) systems. In this method, signals are received in the configured bandwidths of LTE
networks, and the sliding mirror is then correlated. The PSS index is achieved from the local PSS correlation
at peak position after a clear peak value is observed. Analysis and simulation results show that it is applicable
especially to cell edge users in synchronized multi-cell networks to fast acquire PSS with low complexity.
Keywords:

Key words: long term evolution (LTE), primary synchronization signal (PSS), sliding mirror correlation
