Abstract:
There are synchronization signals used in the cell search and synchronization is the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS). Primary Synchronization Signal is used when user equipment (UE) connects to a cell or it is looking to make a cell handover and SSS is used to get information about the cell identity and frame timing properties.Blocks in flow chart are adjusted to each other and feedback control signals guarantee the stability of the receiver sub-system.
For the Long Term Evolution (LTE) receiver, cross-correlation used to estimate the sector identity and enable cell identification. The proposed procedure including fast and enhanced frequency synchronization, timesynchronization, and cell identification.
The results of the scheme show that the fail rate of the overall cell identity must be at least as high as the sector miss rate .If the sector information is correctly acquired by the PSS signal; the cell is estimated correctly in most cases. A significant peak indicates a successful synchronization and cell identification.
