The Modal distribution is a time-frequency distribution specifically designed to model the quasi-harmonic, multi-sinusoidal, nature of music signals and belongs to the Cohen general class of time-frequency distributions. A streaming, object-oriented implementation of the Modal distribution is presented which forms the basis for designing other members of the Cohen class. Implementation of this ...

Orthogonal time frequency space (OTFS) is being pursued in recent times as a suitable wireless transmission technology for use high mobility scenarios. In this work, we propose nonorthogonal multiple acess (NOMA) based OTFS which may be called NOMA-OTFS system and evaluate its performance from level link perspective. The challenge lies the fact that while known resilience to conditions, NOMA yi...

Recently proposed orthogonal time frequency space (OTFS) modulation has been considered as a promising candidate for accommodating various emerging communication and sensing applications in high-mobility environments. In this paper, we propose novel cross domain iterative detection algorithm to enhance the error performance of OTFS modulation. Different from conventional methods, applies basic ...

Sixth-generation (6G) wireless networks are envisioned to provide global coverage for the intelligent digital society of near future, ranging from traditional terrestrial non-terrestri-al networks, where reliable communications in high-mobility scenarios at high carrier frequencies would play a vital role. In such scenarios, conventional orthogonal frequency division multiplexing (OFDM) modulat...
