Technology, particularly Internet of Things (IoT) and Machine Type Communication (MTC), have made a necessity to introduce a new distribution phenomenon. These innovations ask for very high data rates and non-coherent communication. When using inheritance 4th Generation (4G) frameworks, it is not possible to meet these requirements due to the inability to communicate without the use of synchronization. Numerous Orthogonal Frequency Division Multiplexing (OFDM) spectrum replacements, such as the Filtering-OFDM (F-OFDM), have been suggested. Due to the reduction in side-information required due to the synchronization application, a groundbreaking filter based on a minimum 4-term Blackman-Harris window defined by Nuttall is demonstrated numerically in this work. The recommended method outperforms previous design features in terms of spectral ability. In the F-OFDM transitional system, the root-raised-cosine filter is employed. This study, provided a new filter design that is simple to construct and can be completed in an immediate manner. Conventional Cyclic Prefix OFDM (CP-OFDM) showed -50.0 dBW/Hz, while the proposed scheme improved it to -253.2 dBW/Hz.
