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…
Low-Complexity Equalization of Zak-OTFS in the Frequency Domain
Sandesh Rao Mattu, Nishant Mehrotra, Saif Khan Mohammed +2
4G/5G wireless standards use orthogonal frequency division multiplexing (OFDM) which is robust to frequency selectivity. Equalization is possible with a single tap filter, and low-…
Zak-OTFS for Mutually Unbiased Sensing and Communication
Nishant Mehrotra, Sandesh Rao Mattu, Robert Calderbank
Waveforms with ideal ambiguity functions are fundamental to integrated sensing and communication, to active sensing (radar), and to uplink multiple access. We describe a general me…
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…
On the Bit Error Performance of OTFS Modulation using Discrete Zak Transform
Vineetha Yogesh, Vighnesh S Bhat, Sandesh Rao Mattu +1
In orthogonal time frequency space (OTFS) modulation, Zak transform approach is a natural approach for converting information symbols multiplexed in the DD domain directly to time…
