Based on the research of 5G O-RAN architecture and physical layer function,the 5G physical layer LowPHY function module based on Field Programmable Gate Array(FPGA)is designed and implemented.Based on the analysis of the LowPHY function of 5G physical layer,the overall design scheme is developed,and the functional modules are divided into upstream LowPHY module,downstream LowPHY module and Physical Random Access Channel(PRACH)LowPHY module.Aiming at the characteristics of large data processing capacity of LowPHY,FPGA devices with high performance,low delay and low power consumption in data processing are selected.The designed LowPHY function module is integrated with other modules into O-RU unit,which is tested and verified in 5G NR system.The test results show that the design can meet the project requirements and realize the design objectives.
