recommendations! Published in 2019 at "ICT Express"

DOI: 10.1016/j.icte.2018.07.001

Abstract: Abstract The high peak-to-average power ratio (PAPR) is one of the major drawbacks of the orthogonal frequency division multiplexing (OFDM) systems that make non-linear distortion in practical implementation of high power amplifier (HPA). In this… read more here.

DOI: 10.1109/twc.2019.2953540

Abstract: As an approach to reduce the computational complexity of Filtered-Orthogonal Frequency Division Multiplexing (F-OFDM), we removed restrictions on filter lengths in F-OFDM and then applied linear pre- and post-processing for a transmitter and receiver using… read more here.

DOI: 10.3390/jmse13071284

Abstract: The underwater acoustic (UWA) communication system faces challenges due to environmental factors, extensive multipath spread, and rapidly changing propagation conditions. Deep learning based solutions, especially for orthogonal frequency division multiplexing (OFDM) receivers, have been shown… read more here.
