Simulation of 5G Secondary Synchronization Signal Detection
Jing Liang, Jiazhi Hou · 2019
In the mobile communication, the cell search is used to implement time synchronization and frequency synchronization between the user and the cell, and acquire the physical cell identification number. A new synchronization signal structure is defined in the 5G communication system to complete the cell search, wherein the secondary synchronization signal is greatly changed, and the cell group ID in the physical cell identifier can be obtained by the effective secondary synchronization signal sequence detection. This paper focuses on the secondary synchronization signal detection process, and proposes to use the gold sequence characteristics of the secondary synchronization signal to simplify the operation process of obtaining the cell group ID in the physical layer cell identifier. The simulation results show that the proposed improved secondary synchronization signal detection algorithm can reduce the complexity of the cell group ID in the physical cell identifier detection while ensuring the correct rate.
