Abstract
Next-generation wireless communication systems (5G/6G) are intended to offer extensive features and capabilities. Higher data rates, more mobility, reduced latency, and improved service quality are the primary criteria for 5G/6G. The various services and applications expected for 5G/6G will have different expectations for the network’s design. The 5G network is necessary to support massive data traffic and an enormous variety of remote connections. Orthogonal Frequency Division Multiplexing (OFDM) was the most effective choice for 4G networks. However, OFDM has a high Peak to Average Power Ratio (PAPR) and Out of Band (OoB) leakage. More improved Multi-Carrier Modulation (MCM) methods are necessary to meet the expected needs of 5G/6G. So, other MCM approaches are offered to overcome the drawbacks of OFDM. Filtered MCM techniques give feasible solutions for future mobile networks. Multiple access techniques, such as Filter-Bank Multi-Carrier (FBMC), Universal-Filtered Multi-Carrier (UFMC), and Generalized Frequency-Division Multiplexing (GFDM), can be used to analyze the enormous data offered by 5G/6G systems. This paper examines the performance of 5G/6G MCM methods such as FBMC, UFMC and GFDM. After that, we evaluate the results in terms of PAPR, Power Spectral Density (PSD), Computational Complexity (CC), Bit Error Rate (BER) and Spectral Efficiency (SE).
