Non-Orthogonal Multicarrier Waveform for Radar With Communications Systems: 24 GHz GFDM RadCom
IEEE Access, 2019 In this paper, we propose the usage of Generalized Frequency Division Multiplexing (GFDM), a non-orthogonal multicarrier waveform for radar. We presented a novel method that cancels the effect of interference caused by the non-orthogonality of GFDM ...

A DFT-Based Scheme for PAPR Reduction in SR-OFDM Systems
IEEE AccessThis paper focuses on the peak-to-average power ratio (PAPR) reduction in symbol repetition-based orthogonal frequency division multiplexing (SR-OFDM) systems, and a discrete Fourier transform (DFT)-based scheme is proposed to reduce the PAPR of SR-OFDM ...

Understanding the effects of phase noise in orthogonal frequency division multiplexing (OFDM) [PDF]
IEEE Transactions on Broadcasting, 2001 Phase noise must be carefully considered when designing an OFDM-based communication system since an accurate prediction of the tolerable phase noise can allow the system and RF engineers to relax specifications. This paper analyzes the performance of OFDM systems under phase noise and its dependence on the number of sub-carriers both in the presence ...

A new reduced-complexity detection scheme for zero-padded OFDM transmissions
EURASIP Journal on Wireless Communications and Networking, 2011 Recently, zero-padding orthogonal frequency division multiplexing (ZP-OFDM) has been proposed as an alternative solution to the traditional cyclic prefix (CP)-OFDM, to ensure symbol recovery regardless of channels nulls.
