The demand for high data rate, the generation of Internet of Things (IoT), and various Machine Type Communications (MTC) emerged for a new transmission phenomenon. In other words, it is substantial to communicate without synchronization, or synchronization overhead, with mixed signal types. such specifications cannot be covered by the Fourth Generation (4G) systems, which is based on Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM). However, to achieve the specifications of the next generation system, numerous waveform replacements for the CP–OFDM were suggested, Filter Bank Multi–Carrier (FBMC), Generalized Frequency Division Multiplexing (GFDM), Universal Filtered Multi–Carrier (UFMC), and Filtered OFDM (F–OFDM). The filter design occupies essential part in these replacements, thus, in this paper, novel filters are introduced where simulation results show that the proposed filters outperform previous designs in terms of spectral efficiency improved dramatically by releasing the synchronization overhead.

对于新的传输现象，出现了对高数据速率，物联网（IoT）和各种机器类型通信（MTC）的需求。换句话说，在没有同步或同步开销的情况下与混合信号类型进行通信是很重要的。这样的规范不能由基于循环前缀正交频分复用（CP-OFDM）的第四代（4G）系统覆盖。但是，为了达到下一代系统的规格，建议使用CP-OFDM的多种波形替代，滤波器组多载波（FBMC），广义频分复用（GFDM），通用滤波多载波（UFMC）和滤波后的OFDM（F–OFDM）。过滤器设计在这些替代品中占据着至关重要的部分，因此，在本文中，
