Abstract
Next-generation networks are expected to provide a wide range of services and functionalities. These services impose different requirements on the physical layer. Due to ease of implementation, immunity to interference and high data rate support, orthogonal frequency division multiplexing has been the most promising multicarrier waveform to implement on current wireless networks. Whereas, to provide the expected requirements in next-generation networks, more advanced multicarrier modulation techniques are required. Hence, other alternative multicarrier modulation techniques are proposed to address the challenges of orthogonal frequency division multiplexing.
In this work, we analyze performances of candidate multicarrier modulation techniques for next-generation networks such as filter-bank multicarrier and universal filtered multicarrier. To obtain insightful analysis, we first analyze the basic principles and characteristics of each multicarrier modulation technique. Then, we compare the performances in terms of power spectral density (PSD), bit error rate (BER) and spectral efficiency (SE). Besides, the computational complexity of the proposed multicarrier modulation techniques is evaluated. Finally, numerical simulation is done to validate the theoretical analysis. The results show that FBMC has minimum out-of-band emission and this helps to be almost insensitive to multiuser interference to support different use cases in the same bands. Whereas, UFMC reveals to be the most promising waveform which gives close to OFDM performance with better out-of-band emission.
