In this paper, we analyze the impacts of timing offset (TO), carrier frequency offset (CFO),
and phase noise in orthogonal frequency division multiplexing (OFDM) and generalized …

In this paper, a new matrix-based characterization of generalized-frequency-division-
multiplexing (GFDM) transmitter matrices is proposed, as opposed to traditional vector …

Abstract 5G will have to cope with a high degree of heterogeneity in terms of services and
requirements. Among these latter, flexible and efficient use of all available non-contiguous …

The fifth generation (5G) of mobile cellular systems will demand an unprecedented flexibility
of the physical layer (PHY). Several approaches are being proposed based on theoretical …

Diverse requirements are foreseen for the 5G cellular system and new waveforms are being
researched for the physical layer (PHY), where the non-orthogonal Generalized Frequency …

In uplink multiuser systems, different timing offset (TO) and/or carrier frequency offset (CFO)
of multiple users cause multiuser interference (MUI) to a desired user. In this paper, we …

Sparse code multiple access (SCMA) is one type of non-orthogonal multiple access
techniques for the fifth-generation wireless communication networks. Existing multiuser …

Generalized frequency division multiplexing (GFDM) is one of the new waveforms with
several attractive features such as lower out of band radiation, higher spectral efficiency, and …

A new circularly pulse-shaped (CPS) precoding orthogonal frequency division multiplexing
(OFDM) waveform, or CPS-OFDM for short, is proposed in this paper. CPS-OFDM …
