In this paper, we propose an enhanced universal filtered orthogonal frequency division multiplexing (eUF- OFDM) to achieve low out-of-band emission (OOBE) while maintaining high communication quality under the long-delay multipath fading environment by combinedly using a cyclic prefix (CP) and a filter with short-transition time. The proposed eUF- OFDM can suppress the OOBE at channel-edge by 25 dB compared to the conventional OFDM. Furthermore, the proposed eUFOFDM improves the signal-to-noise ratio (SNR) to achieve block-error-rate (BLER) = 10 ^-3 by 1.3 dB compared to the conventional UF-OFDM under the long- delay multipath fading mobile environment.
