  3. Rayleigh fading - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_fading

    Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices. It is based on a Rayleigh distribution and applies when there is no dominant line of sight between the transmitter and receiver.

  4. Coherence time (communications systems) - Wikipedia

    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 OFDM. [1]
