A low-complexity eigenvalue decomposition based-GFDM transceiver for self-interference elimination in next-generation wireless systems

Journal of Information and Telecommunication
Generalized Frequency Division Multiplexing (GFDM) is a flexible multi-carrier scheme and has a potential to overcome some of the limitations of orthogonal frequency division multiplexing (OFDM) specifically for diverse use cases of beyond 5G (B5G)/ 6G ...

Reduction In Inter-Symbol Interference Using Linear Prolate Functions

, 2015
In a baseband system, the digital information signal required to be transmitted over a channel, has a wide frequency spectrum. This wide frequency spectrum gets attenuated due to the band limited response of the filters utilized for communication.

Performance of the split-symbol moments SNR estimator in the presence of inter-symbol interference

, 1989
The Split-Symbol Moments Estimator (SSME) is an algorithm that is designed to estimate symbol signal-to-noise ratio (SNR) in the presence of additive white Gaussian noise (AWGN). The performance of the SSME algorithm in band-limited channels is examined.

Differential Faster-Than-Nyquist Signaling

IEEE Access, 2018
In this paper, we propose a novel differential faster-than-Nyquist (DFTN) signaling concept that allows us to dispense with any channel estimation at the receiver, while benefiting from a rate boost specific to faster-than-Nyquist (FTN) signaling.
