Accelerated Detection Schemes for PSS in 5G-NR

Future generation networks are expected to support high data rate with very low latency so as to enable key services such as massive machine type communications, internet of things (IoTs) etc. Apart from the specific requirements set by different standard bodies in fulfilling these key services, there are key enabling features and processes that need overhauling to enhance the performance. One such process is frame synchronization between the gNB and the UE, which essentially is the first step towards granting resources for information transmission. In this paper, we thus present novel detection schemes that help in faster detection of the PSS at the UE which in turn helps in fast synchronization. Compared to the existing method, the proposed schemes not only enable in the faster detection but also enhances the detection performance at low signal-to-noise ratio (SNR). Further, simulation results are shown to corroborate the efficacy of the proposed algorithms.
