Low-complexity Equalization of Zak-OTFS Via Neumann Series
Vineetha Yogesh, Saif Khan Mohammed, Sandesh Rao Mattu +2
We describe a general method for selecting an orthonormal basis of carrier waveforms that aligns the basis with delay / Doppler characteristics of a wireless channel. We show that…
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…
MIMO Zak-OTFS: Channel Estimation, Detection, and Throughput Analysis
Faraz Barati, Rahul Kumar Jaiswal, Saif Khan Mohammed +2
Zak-Orthogonal Time Frequency Space (Zak-OTFS) modulation has demonstrated substantial performance gains over cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM) in…
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…
Does 6G Need a New Waveform: Comparing Zak-OTFS with CP-OFDM
Imran Ali Khan, Saif Khan Mohammed, Ronny Hadani +6
Across the world, there is growing interest in new waveforms, Zak-OTFS in particular, and over-the-air implementations are starting to appear. The choice between OFDM and Zak-OTFS…
