Performance Analysis of UFMC and its Comparison with CP-OFDM

Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) is used in 4G communication systems. There are problems in 4G Waveform such as out of band emission and lower spectral efficiency which forces to explore new waveforms for Fifth Generation (5G). Universal Filtered Multi-Carrier (UFMC) is one such air interface which is analysed in this work and compared with CP-OFDM highlighting the merits of the candidate modulation scheme for 5G communication systems. This work presents the comparison UFMC and CP-OFDM on the basis of Peak to Average Power Ratio (PAPR) and Power Spectral Density (PSD) and analyse the performance of UFMC in Additive White Gaussian Noise (AWGN) channel using MATLAB. It is found that 40 dB reduction in out-of-band emission is seen in UFMC when compared to CP-OFDM with negligible increase in PAPR.
