Low complex primary and secondary synchronization signal structure design for LTE systems

Abstract

This electronic Synchronization plays a vital role in enhancing the overall performance of the LTE system. In this paper, both Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) are considered and an attempt is taken to modify their structures to reduce the computational complexity and time. In PSS, it is spotlight to reduce the computational time by dividing the Zadoff-chu (ZC) sequence into four segments instead of using the ZC sequence as such as in conventional systems. In SSS, a modified signal structure to reduce the computational time is proposed. The performance of proposed PSS and SSS structures is compared with existing approaches of LTE system.
