OTFS technology research and prospect
Recently, a new multi-carrier modulation technique termed orthogonal time frequency space (OTFS) was proposed.In the OTFS modulation, the data symbols are modulated at the delay-Doppler plane and spread on all the time-frequency resource elements with the inverse symplectic finite Fourier transform....

| description | Recently, a new multi-carrier modulation technique termed orthogonal time frequency space (OTFS) was proposed.In the OTFS modulation, the data symbols are modulated at the delay-Doppler plane and spread on all the time-frequency resource elements with the inverse symplectic finite Fourier transform.Compared with the conventional orthogonal frequency division multiplexing (OFDM) technique, the OTFS modulation performs better in the time-varying and frequency-selective channel.The state of art of OTFS was reviewed and summarized.Simulation results were presented to demonstrate the performance advantage of OTFS over the conventional OFDM.The remainder problems of multi-accessing, channel estimation and linear equalization in OTFS was given.The application of OTFS signal in joint Radar and communication system was also analyzed. |
