Holistic Evaluation of UFMC, FBMC, and F-OFDM Modulation Schemes for Enhanced Spectral Efficiency in 5G Communication Networks

For the purpose of the current requirement for high spectrum efficiency and low interference, the modulation techniques need to be developed for 5G communication networks. This paper provides an extensive analysis of the performance of three highly developed modulation techniques namely, UFMC, FBMC, and F-OFDM to enhance the spectral efficiency of 5G networks. To enable versatile analysis and fair comparison of the spectrum containment, side-lobe leakage and computational complexity of each of the proposed schemes the work employs a broad system model that uses power spectral density (PSD) and impulse response analysis. From the simulation studies, UFMC and FBMC are more appropriate for high density 5G scenarios since they have higher spectral efficiency and low side lobe leakage as compared to OFDM. also shown here that proves that F-OFDM is a successful strategy by which the computational complexity of the system may be reduced without much compromising the acceptable spectral efficiency. From each modulation technique, an assessment of the system's performance is carried out based on parameters such as PSD, computational complexity, and spectrum efficiency measurements. The results shown above indicate how effective UFMC and FBMC are in achieving higher spectrum efficiency, while F-OFDM is a reasonable mid-point between complexity and practical effectiveness.
