基于分块互相关的5G PSS同步算法研究与仿真
Research and simulation on synchronization algorithm of PSS in a 5G system based on block cross-correlation
摘要
Abstract
In response to the downlink synchronization requirements of the user equipment (UE) or third-party radio equipment in fifth-generation (5G) mobile communication systems,a synchronization algorithm of primary synchroni-zation signal (PSS) was designed and developed in the 5G system based on block cross-correlation.According to the new characteristics of the 5G synchronization charmel and broadcast channel,starting from the traditional downlink synchronization algorithm of long-term evolution (LTE),the detection performance of the algorithm under a low signal-to-noise ratio(SNR) is improved by introducing an incoherent accumulation,and the new scheme of joint coarse frequency offset estimation is used to improve the frequency offset estimation performance.Finally,the performance of the proposed synchronization algorithm is verified by conducting a simulation on a 5G downlink simulation platform based on MATLAB software.Simulation results show that the improved downlink synchronization algorithm has stable performance in the tapped delay line-C (TDL-C) and additive white Gaussian noise (AWGN) channels with large frequency deviation and low SNR.关键词
