The work presents real-time emulation techniques for testing Centralized Radio Access Network (C-RAN) components using frequency-domain processing on general-purpose processors. From the abstract: the proposal exhibits an improvement of one order of magnitude on generic x86 computers in the average computation time of the multipath channel, compared to the existing time-domain approach in downlink and uplink transmissions.
