Description: 在3GPP系统中，初始小区搜索包含两步，这两步要用到主同步信号和辅同步信号。这篇文章介绍了一种辅同步信号检测的方法。-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.

中存在整数倍频偏，则由于时域的相位旋转，主同步信号将很难用传统的相关算法检测到。提出一种主同步信号与整数倍频偏联合检测的方法，即使存在整数倍频偏，也能得到正确的符号定时。辅同步信号采用的是非相干的差分相关检测[2]，仿真表明，与传统的匹配滤波算法相比，可以有效的对抗信道时延扩展和载波频偏，适用于高速场景下时分双工(Time Division Duplex，TDD)LTE系统的同步。-In LTE systems, the initial cell search process is completed by detecting the primary synchroniza-tion signal and the secondary synchronization signal. The searching results include cell ID group, symbol timing, frequency offset estimation, intra group cell ID and frame timing[1]. However, if integer frequency offset presents in the received signal, due to time-domain phase rotation, the primary synchronization signal will be difficult to detected using the conventional correlation algorithm. A new joint detection method for integer frequency offset and primary synchronization signal is proposed, which can get the correct symbol timing even if the presence of integer frequency offset. Secondary synchronization signal is processed using the differential non-coherent correlation detection method[2]. Simulations show that compared with the tradi-tional matched filtering algorithms, it can effectively combat the channel delay spread and carrier frequency offset and especially suitable for
