Abstract

In this paper, an effective algorithm for detecting the sector ID and ICFO together via the PSS-matching process is presented. In the conventional scheme, the commonly used differential correlation for PSS detection in frequency domain is applied. Its performance is compromised by the squaring noise. To remedy this shortcoming, a partial correlation scheme for PSS detection, including the theoretical deduction and analysis, is proposed. Compared with conventional schemes, the proposed scheme can detect both the sector ID and ICFO with higher accuracy and much lower complexity. The performance superiority of the proposed scheme is confirmed by the simulation results. The performance of the techniques discussed is compared through simulation, as well as through considerations of their relative computational complexity.
