This book presents a discourse on a potential waveform for 6G--namely Orthogonal Time Frequency Space (OTFS) Modulation.

OTFS has a distinct feature when compared to earlier generation waveforms such that an information bearing signal is placed in the delay Doppler domain as opposed to the usual placement of such signals in the time-frequency domain. This unique feature of OTFS enables it to overcome several disadvantages of a very popular and highly successful waveform, namely Orthogonal Frequency Division Multiplexing (OFDM). OTFS is known to be more resilient to frequency offset than Doppler which is one of the key drawbacks of OFDM. With this feature, OTFS can support higher mobility as well as higher frequency bands of operation which is also one of the key requirements of the next generation wireless communication technologies. The implementation complexity of OTFS remains comparable to that of OFDM. OTFS provides significant SNR advantage, higher resilience, lower PAPR, lower out of band signal leakage and higher multi-user spectral efficiency than that of OFDM. This book addresses

  • Fundamental signal model of OTFS
  • Receiver design for OTFS
  • Channel estimation in OTFS
  • Multiple Access through non-orthogonal multiple access (NOMA-OTFS)
The contents of the books are primarily the outcome of the research work done at the G. S. Sanyal School of Telecommunications, Indian Institute of Technology Kharagpur, Kharagpur, India.

Orthogonal Time Frequency Space Modulation: A Waveform for 6G is ideal for personnel in the wireless communication industry as well as academic staff and master/research students in electrical engineering with a specialization in wireless communications.
