[Communication-Mobile] SSS-detection-method DL : 0: 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.
