Simulation performance analysis of FBMC-OQAM system based on frequency spreading

To cater to the escalating demand for information transmission in today's digital society, prioritizing the development of high-speed wireless communication technologies is essential. Among these, Orthogonal Frequency Division Multiplexing (OFDM) has emerged as one of the most widely adopted multicarrier technologies in the communications arena. OFDM stands out with its high transmission rate and robust anti-interference capabilities. However, it has certain limitations, including low spectrum utilization and a lack of flexibility, which restrict the growth of communication technology. In response to these challenges, Filter Bank-based Multicarrier (FBMC) technology, a cornerstone of the fifth generation (5G) of mobile communication, presents itself as an effective solution to existing multicarrier technology issues. By leveraging Offset Quadrature Amplitude Modulation (OQAM), the FBMC-OQAM system boasts impressive resistance to subcarrier interference and high spectral efficiency. Although the FBMC-OQAM technique is still in its nascent stages, it holds promising potential. Its adoption can significantly enhance communication systems' performance by addressing interference and spectrum efficiency issues plaguing current technologies. Consequently, it is anticipated to become a cornerstone technology in mobile communication's future landscape. As we explore its full potential, the ongoing research in this area is expected to lead to breakthroughs that could redefine the way we think about wireless communications.
