Current researchers point out that with the arrival of new radio our cellular system will suffer important evolutionary changes. In this work, new users necessities and principal emerging technologies providing a solution for the implementation and deployment of new radio generation are described, from the beginnings of 2G and 3G, the consolidation of Long Term Evolution and Advanced Long Term Evolution, to 5G (fifth generation). The main study objective is to understand why LTE can not satisfy new mobile communications challenges and how with the arrival of the new radio we can reach ambitious results. As a consequence, new waveform requirements are needed. There are three Orthogonal Frequency Division Multiplexing variations that have real chances to become the new waveform, called Cyclic Prefix OFDM, Filtered OFDM, Filter Bank Multi-Carrier and Universal Filtered Multi-Carrier. The aim of the MATLAB simulation is to compare these waveforms implementations and take conclusions about the best application of each one. F-OFDM candidate improves significantly the spectral efficiency compare with OFDM due to the filtering techniques by reducing OOB emissions, and achieves good BER numerical results. Therefore, it is a good technology to have in account for enhanced Mobile Broadband and massive Machine Type Communications applications. Although it needs CP insertion so it loses spectral efficiency and does not optimise the resources. FBMC waveform achieves the highest spectral efficiency and also has good Bit Error Rate curves. Therefore, it is perfect for applications such as eMBB where high spectral efficiency is critical, ultra-reliable and Low Latency Communications where high reliable links are needed and also mMTC because of its high energy efficiency. This candidate also achieves best Peak-to-Average Power Ratio values, i.e. 10.9 dB. UFMC candidate can be used for mMTC applications due its non-orthogonal waveform which facilitate short data burst communications. Finally, as a conclusion, there is no waveform able of meeting all the requirements of the new radio. Therefore, the new air interference must be flexible to support different types of waveforms, each of which brings its advantages. Ingeniería de Sistemas de Comunicaciones
