Hardware Testbed for Sidelink Transmission of 5G Waveforms without Synchronization

This paper details a hardware testbed conceived for studying the impact of the lack of synchronism between transmitters on several 5G waveform candidates, which is of special relevance for car-to-car communications. The experimental results show that a proper fitting of waveforms in a software-defined platform would permit increasing the range of communication between cars without peer-to-peer synchronization, paving the way for the real development of collision avoidance messages.
