A Comparative Analysis of Multicarrier Waveforms for Future Wireless Communications

Beyond Orthogonal Frequency Division Multiplexing, there has been a lot of study done since there is a requirement for enhanced waveforms in 5G networks. For 5G, many filtered multi-carrier transmission systems, such as filter-OFDM and filter bank multicarrier modulation, have been suggested, each with its own set of advantages and disadvantages. This article seeks to give a thorough comparative study of different waveforms, allowing for a comparative evaluation of their performance on an overall basis. The study comprehensively assesses various performance metrics, including peak-to-average power ratio, out-of-band leakage power, bit error rate over wireless channels, the impact of carrier frequency offset, and spectral efficiency. These findings will be useful in determining which waveform to use for the future generation of mobile communication systems.
