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.
