Computational Complexity for Simplified Universal Filtered Multi-Carrier (UFMC) Wireless Transmitter

The Universal Filtered Multi-Carrier (UFMC), which combines the benefits of Filter Bank Multicarrier (FBMC) and Orthogonal Frequency Division Multiplexing (OFDM), is one of the prospective waveform technologies for future wireless networks. Despite these advantages, the UFMC system has a more complex implementation than the OFDM system. This paper describes a method for simplifying the transmitted UFMC symbol in the time domain, which is implemented like OFDM without filtering operations, reducing the computational and hardware complexity of the UFMC transmitter. The simulation results show that the proposed model gives the same system performance with reduced computational complexity.
