5G millimeter wave cell search algorithm with beam sweeping
Due to the high carrier frequency of the 5G millimeter wave,a large initial access frequency may cause inaccurate time-frequency synchronization at the transmitting and receiving ends and incorrect detection of the physical layer cell identifier.A cell search scheme for 5G millimeter waves to send s...

| description | Due to the high carrier frequency of the 5G millimeter wave,a large initial access frequency may cause inaccurate time-frequency synchronization at the transmitting and receiving ends and incorrect detection of the physical layer cell identifier.A cell search scheme for 5G millimeter waves to send synchronization signals in a beam sweeping mode at high frequencies was analyzed and simulated.Specifically,a multi-directional synchronization signal block sent by a DFT codebook at the base station side was proposed.The terminal used an omnidirectional antenna to receive multi-beam signals and used a series of synchronization algorithms to complete time,frequency synchronization,and physical layer cell identification.Simulation results show that the proposed main synchronization signal detection algorithm with cross-correlation of pre-stored integer frequency offset and received signal has good cell search performance on 5G millimeter-wave channels. |
