OTFS-IM-Assisted Non-Terrestrial Networks Relying on Autoencoder-Aided Soft-Decision Detection
Xinyu Feng, Chao Zhang, Mohammed EL-Hajjar +2
Orthogonal Time Frequency Space ({OTFS}) modulation offers significant advantages over Orthogonal Frequency Division Multiplexing ({OFDM}), particularly in high speed environments.…
Amalgamated CHIRP and OFDM for ISAC
Pankaj Kumar, Mohammed El-Hajjar, Ibrahim A. Hemadeh +4
Integrated Sensing and Communication (ISAC) requires the development of a waveform capable of efficiently supporting both communication and sensing functionalities. This paper prop…
Delay-Doppler-Domain Channel Estimation and Reduced-Complexity Detection of Faster-than-Nyquist Signaling Aided OTFS
Zekun Hong, Shinya Sugiura, Chao Xu +1
We conceive a novel channel estimation and data detection scheme for OTFS-modulated faster-than-Nyquist (FTN) transmission over doubly selective fading channels, aiming for enhanci…
MIMO-AFDM Outperforms MIMO-OFDM in the Face of Hardware Impairments
Zeping Sui, Zilong Liu, Leila Musavian +3
The impact of both multiplicative and additive hardware impairments (HWIs) on multiple-input multiple-output affine frequency division multiplexing (MIMO-AFDM) systems is investiga…
