Abstract :
In 3GPP long term evolution (LTE) system, initial cell search procedure comprises two steps using primary synchronization signal (PSS) and secondary synchronization signal (SSS). This paper presents SSS detection method for second step of initial cell search. In general, coherent detection using estimated channel frequency response (CFR) at PSS is used for SSS detection, but performance degradation is occurred by difference of channel between PSS and SSS in time division duplex (TDD) mode. Thus we propose non-coherent detection using partial correlation and differential correlation. Moreover, we consider cyclic-prefix (CP) detection algorithm that uses CP and its repetition part of data symbol, and we investigate influence of CP detection in SSS detection process.
