The Fifth Generation of mobile communications (5G) is being standardized in order to reach higher data rates and deploy new services. In this frame, researchers are looking for possible waveforms to improve the air interface. Orthogonal Frequency Division Multiplexing (OFDM) has high Out-of-Band Emissions (OBE) which force us to leave wider guard bands, reducing so the spectral efficiency. Recently, we have proposed the Power Adapted-OFDM which is capable of fulfilling the requirements of 5G and avoids the main issues of other proposed candidates. OpenAir Interface (OAI) is a powerful and flexible wireless technology platform based on the Long-Term Evolution (LTE) ecosystem, which offers the possibility of evaluating the effects of introducing a new technology on the entire mobile communication system. In this paper, we will evaluate and show the performance of the proposed technique using the OAI.
