On multipath fading channels at high SNR [PDF]
2008 IEEE International Symposium on Information Theory, 2008 This paper studies the capacity of discrete-time multipath fading channels. It is assumed that the number of paths is finite, i.e., that the channel output is influenced by the present and by the L previous channel inputs. A noncoherent channel model is considered where neither transmitter nor receiver are cognizant of the fading's realization, but ...

Journal of Electrical, Electronics and Informatics, 2020 The characteristics of wireless channel are determined by multipath propagation. The transmitted signal will be scattered so that it produces fading. Fading influenced by multipath component will cause delay spread which damages the signal.

Effective Capacity Analysis Over Generalized Composite Fading Channels
IEEE Access, 2020 A performance analysis of the effective capacity in two recently proposed generalized composite fading channels, namely $\kappa $ - $\mu $ /inverse gamma and $\eta $ - $\mu $ /inverse gamma composite fading channels, is conducted. To this end, accurate

Coastal multipath fading [PDF]
IEEE Transactions on Antennas and Propagation, 1981 While flight testing airborne satellite communication systems, two-ray multipath fading has been regularly encountered at low satellite elevation angles during over water flights. In addition, an unexpectedly fast multipath fading was experienced as the aircraft transitioned from over land to over water. This unusual multipath fading occurred at medium
