Filtre banka çok taşıyıcı 5G dalga formu üzerindeki frekans bant dışı emisyonların azaltılması

This research is dedicated to a comprehensive examination of multi-carrier digital modulation, particularly focusing on the widely used Orthogonal Frequency Division Multiplexing (OFDM) technique. The core aim of this investigation is to delve into the development of Filter Bank Multicarrier (FBMC) systems with the explicit objective of reducing undesirable emissions in the carrier wave within the context of 5G networks. Our primary motivation is the pressing need for more spectrally efficient and interference-resistant modulation techniques in the evolving landscape of wireless communications. A critical facet of our analysis is an extensive comparative study that systematically juxtaposes FBMC against alternative modulation methods. This comparative assessment offers a detailed and nuanced understanding of FBMC's relative advantages and limitations in comparison to its counterparts. To substantiate our findings and assess the practical viability of FBMC, we conducted real-world implementations leveraging the computational capabilities of MATLAB. These practical experiments involved signal enhancement measures aimed at achieving optimal performance. The results obtained through these empirical investigations are encouraging, indicating elevated efficiency levels and notable enhancements in transmission quality. These empirical outcomes lend credence to the potential of FBMC as a compelling solution in the realm of advanced wireless communication systems, particularly within the evolving paradigm of 5G networks
