A wide range of potential use cases will describe future wireless networks. In order to achieve this, time-frequency resources must be dynamically assigned, which is difficult for traditional Orthogonal Frequency Division Multiplexing (OFDM). Therefore, OFDM improvements like filtering or windowing are needed. On the other hand, a multicarrier method like Filter Bank Multi-Carrier (FBMC) can be employed. Several prototype filters, including Hermite, PHYDYAS, and Root Raise Cosine (RRC), are used in this work to develop the framework for FBMC. Time-frequency efficiency will be determined for each user in the same band by adjusting the subcarrier spacing. The performance of the Signal to Interference Noise Ratio (SIR) is calculated for FBMC using varying subcarrier spacing and compared with different multicarrier transmission methods such as f-OFDM (filtered OFDM), CP-OFDM, UFMC (Universal Filter Multi Carrier), Weighted Overlap and Add (WOLA). FBMC outperforms among all these multi carrier modulations and proven that it is suitable even for low latency transmissions. time-frequency resources prototype filters Filter Bank Multi-Carrier (FBMC) subcarrier spacing Signal to Interference Noise Ratio (SIR) Full Text Additional Declarations No competing interests reported.
