LTE) and Fourth Generation (4G) are the enhancing techniques that contribute the progress of wireless communication
systems. The most effective way to save resources in 5G is to make efficient use of all existing discontinuous spectrums,
which maximizes Spectrum Efficiency (SE). A valid comparison of many 5G MCM techniques is made in this work,
namely Universal Filter Multi Carrier (UFMC), Filter Bank Multi Carrier (FBMC) and Orthogonal Frequency Division
Modulation (OFDM). Various Key Performance Indicators (KPI) such as Bit Error Ratio (BER), Signal to Interference
Ratio (SIR), Power Spectral Density (PSD) and ratio between Peak Power and Average Power, Throughput, and Spectral
Efficiency (SE) are evaluated and compared under various realistic channels. UFMC Modulation technique is compatible
with existing channel estimation and detection techniques and further improves SE. The SE of FBMC has been improved by
2% with Hermite filter when compared to PHYSDAS, RRC prototype filters. It has been observed that FBMC offered better
SIR, Throughput, also a complex design of filter reduced BER and PAPR.
