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…
Discrete Radar based on Modulo Arithmetic
Nishant Mehrotra, Sandesh Rao Mattu, Saif Khan Mohammed +2
Zak-OTFS is modulation scheme where signals are formed in the delay-Doppler (DD) domain, converted to the time domain (DD) for transmission and reception, then returned to the DD d…
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…
Zak-OTFS based Multiuser Uplink in Doubly-Spread Channels
Imran Ali Khan, Saif Khan Mohammed, Ronny Hadani +2
Wireless users with different characteristics will be expected to share spectrum in next generation communication networks. One of the great strengths of wireless networks based on…
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…
Low-Complexity Frequency Domain Equalization of Zak-OTFS in Doubly-Spread Channels
Saif Khan Mohammed, Sandesh Rao Mattu, Nishant Mehrotra +2
We communicate over wireless channels by first estimating and then equalizing the effective channel. In Zak-OTFS (orthogonal time frequency space) modulation the carrier waveform i…
