Primary Synchronization Signal in LTE/LTE-Advanced Systems

The study is aimed at improvement of Primary Synchronization Signal (PSS) detection in synchronization procedure. The proposed algorithm modifies PSS structure in Long Term Evolution / Long Term Evolution - Advanced (LTE/LTE-A) systems and exploits cross correlation properties of Zadoff-Chu sequences in the other way. We focused on FDD duplexing mode in downlink of LTE radio frame with normal cyclic prefixes and also we applied multipath fading channel in the estimations. Simulation results show that when channel experiences noisy environment or low SNR, the algorithm can work better.
