Experimental Evaluation of 5G vRAN Function Implementation in an Accelerated Edge Cloud

Disaggregated next generation eNodeB (gNB) largely benefits from offloading selected virtu-alized Distributed Unit (vDU) functions into a field programmable gate array (FPGA). Results show that the FPGA-based IFFT and cyclic-prefix addition processing time is faster than dual-core high-end CPU on longer OFDM symbol size with lower power consumption.
