dc.description.abstractThe rapid evolution of wireless communication systems has increased the need for advanced waveform designs that can support higher data rates, lower latency, and better spectral efficiency. Among several candidates, Universal Filtered Multicarrier (UFMC) has emerged as a promising solution due to its ability to minimize out-of-band emissions and operate effectively in asynchronous and fragmented spectrum scenarios. In this thesis, we evaluate UFMC in comparison to the conventional Orthogonal Frequency Division Multiplexing (OFDM), which has been the dominant waveform in 4G and 5G systems. The study includes a detailed simulation-based performance analysis using MATLAB. We investigate key performance metrics such as Power Spectral Density (PSD), Peak-to-Average Power Ratio (PAPR), Out-of-Band Emissions (OOBE), Bit Error Rate (BER), and Symbol Error Rate (SER) under various modulation schemes (4-QAM to 256-QAM) and a Rician fading channel. The Simulation results demonstrate that UFMC achieves better spectral containment, more stable PAPR behavior with high-order modulations, and improved OOBE suppression outperforming OFDM in several scenarios relevant to 5G and future 6G requirements. This work highlights UFMC’s advantages and limitations and confirms its potential as a strong waveform candidate for next-generation wireless systems.
