Error probability and error stream properties in channel with slow Rician fading [PDF]
, 2003 In a radio communication channel wave parameters fluctuate randomly. The signal envelope undergoes deep fades. When binary information is transmitted through such a channel, fading causes random variation of probabilities of error associated with the ...

On the MIMO Capacity for Distributed System under Composite Rayleigh/Rician Fading and Shadowing
International Journal of Antennas and Propagation, 2015 Wireless channels are commonly affected by short-term fading and long-term fading (shadowing). The shadowing effects must be taken into account also when mobility is present in the wireless scenario.

Simple Expression of Ergodic Capacity for Rician Fading Channel
IEICE Transactions on Communications, 2010 In this letter, a new exact expression of the ergodic channel capacity for a Rician fading channel is provided that is written in terms of exponential integral and incomplete gamma function. Also, a good approximation of the Rician fading channel capacity is derived from the exact expression and its accuracy is numerically verified.

Capacity of κ-μ Shadowed Fading Channels
International Journal of Antennas and Propagation, 2014 The ergodic capacity of fading channels modeled with a κ-μ shadowed distribution is investigated to derive closed-form expressions. The κ-μ shadowed distribution is of particular interest because it contains, as special cases, other classical ones like ...
