Inter-frame Channel Prediction for Zak-OTFS
Muhammad Ubadah, Saif Khan Mohammed
Zak-Orthogonal Time Frequency Space (OTFS) modulation is known to be robust to Doppler spread in high mobility scenarios when compared to Orthogonal Frequency Division Multiplexing…
Improving Doppler Resilience of OFDM through Delay-Doppler Sensing
Danish Nisar, Saif Khan Mohammed, Muhammad Ubadah +2
The performance of traditional CP-OFDM degrades severely in doubly-spread wireless channels due to inter-carrier interference (ICI). In this paper, we propose DD domain sensing bas…
Zak-OTFS over CP-OFDM
Saif Khan Mohammed, Saurabh Prakash, Muhammad Ubadah +7
Zak-Orthogonal Time Frequency Space (Zak-OTFS) modulation has been shown to achieve significantly better performance compared to the standardized Cyclic-Prefix Orthogonal Frequency…
Precoded Zak-OTFS for Per-Carrier Equalization
Saif Khan Mohammed, Amit Kumar Pathak, Muhammad Ubadah +3
In Zak-OTFS (orthogonal time frequency space) modulation the carrier waveform is a pulse in the delay-Doppler (DD) domain, formally a quasi-periodic localized function with specifi…
Zak-OTFS to Integrate Sensing the I/O Relation and Data Communication
Muhammad Ubadah, Saif Khan Mohammed, Ronny Hadani +3
The Zak-OTFS input/output (I/O) relation is predictable and non-fading when the delay and Doppler periods are greater than the effective channel delay and Doppler spreads, a condit…
Zak-OTFS and Turbo Signal Processing for Joint Sensing and Communication
Jinu Jayachandran, Muhammad Ubadah, Saif Khan Mohammed +3
The Zak-OTFS input/output (I/O) relation is predictable and non-fading when the delay and Doppler periods are greater than the effective channel delay and Doppler spreads, a condit…
