WebDue to the increased demand for data rate, flexibility, and reliability of 5G cellular systems, new modulation formats need to be considered. A recently proposed scheme, Orthogonal Time Frequency Space (OTFS), offers various advantages in particular in environments with high frequency dispersion. Such environments are encountered, e.g, in mm-wave systems, … WebOTFS, which is a revolutionary new modulation technique, was originally proposed by Hadani et al. in [5]- [7], which clearly illustrated its advantages over the well-known OFDM …
WebJul 30, 2024 · More importantly, OTFS enjoys the full time-frequency diversity of the channel, which is the key to provide reliable transmissions for the future 6G and high mobility communications. This workshop aims at bringing together academic and industrial researchers in an effort to identify and discuss the major technical challenges, recent … Orthogonal Time Frequency Space (OTFS) is a 2D modulation technique that transforms the information carried in the Delay-Doppler coordinate system. The information is transformed in the similar time-frequency domain as utilized by the traditional schemes of modulation such as TDMA, CDMA, and … See more OTFS is a modulation scheme where each transmitted symbol experiences a near-constant channel gain even in channels at high carrier frequencies (mm-wave) or with high Doppler. This OTFS signal is well localized in both … See more A pulsone (stands for pulse + tone) is the time realization of a quasi-periodic pulse in delay-Doppler and it serves as the carrier waveform of the OTFS modulation format. Of particular … See more The idea for OTFS was first patented in 2010 by Ronny Hadani and Shlomo Rakib and transferred to Cohere Technologies Inc in 2011. In December 2024, during the inaugural 6G … See more Low complexity equalization has been proposed based on Message Passing (MP), Markov Chain Monte Carlo (MCMC), and Linear … See more It is impossible to transmit an ideal pulse shape due to the time-frequency uncertainty principle. This motivated some works for practical pulse shaped OTFS systems. See more OTFS offers several advantages in particular environments where the dispersion is at high frequency. Environments such as these are encountered in mm-wave systems, due to both larger Doppler spreads and higher phase noise. … See more
