Comparative analysis of cell search schemes in Long Term Evolution Systems

In Long Term Evolution (LTE) systems, cell search is performed by each User Equipment (UE), to detect the cell identity. The received subframe index and radio frame timings in the downlink are also acquired. Cell search is performed using the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) in a hierarchical manner. In this paper we have simulated the schemes for PSS and SSS detection of cell identity and subframe index using Linear Correlation and Circular Correlation. The probability of PSS and SSS detection for both schemes is compared by Monte Carlo Simulation Method.
