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…
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…
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…
Zak-OTFS with Interleaved Pilots to Extend the Region of Predictable Operation
Jinu Jayachandran, Imran Ali Khan, Saif Khan Mohammed +3
When the delay period of the Zak-OTFS carrier is greater than the delay spread of the channel, and the Doppler period of the carrier is greater than the Doppler spread of the chann…
Delay-Doppler Signal Processing with Zadoff-Chu Sequences
Sandesh Rao Mattu, Imran Ali Khan, Venkatesh Khammammetti +4
Much of the engineering behind current wireless systems has focused on designing an efficient and high-throughput downlink to support human-centric communication such as video stre…
