Zero-padding or cyclic prefix for MDFT-based filter bank multicarrier communications


In this paper, the problem of channel equalization in modified discrete Fourier transform (MDFT)-based filter-bank multicarrier system (FBMC) is addressed. Two different system models based on padding zeros or using cyclic prefix in each transmitted block are presented. The proposed systems utilize IFFT/FFT blocks embedded in an MDFT-FBMC system.
