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…
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…
Waveform for Next Generation Communication Systems: Comparing Zak-OTFS with 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…
Closed-Form Expressions for I/O Relation in Zak-OTFS with Different Delay-Doppler Filters
Arpan Das, Fathima Jesbin, Ananthanarayanan Chockalingam
The transceiver operations in the delay-Doppler (DD) domain in Zak-OTFS modulation, including DD domain filtering at the transmitter and receiver, involve twisted convolution opera…
