Weibull Fading
Weibull fading, named after Waloddi Weibull, is a simple statistical model of fading used in wireless communications and based on the Weibull distribution In probability theory and statistics, the Weibull distribution is a continuous probability distribution. It is named after Swedish mathematician Waloddi Weibull, who described it in detail in 1951, although it was first identified by Maurice Re .... Empirical studies have shown it to be an effective model in both indoor and outdoor environments. In 2005, a theoretical model for a particular class of Weibull distributions was described by Sagias and Karagiannidis, who also analyzed channel capacity of a wireless channel in the presence of Weibull fading.

Waloddi Weibull
Ernst Hjalmar Waloddi Weibull (18 June 1887 – 12 October 1979) was a Swedish civil engineer, materials scientist, and applied mathematician. The Weibull distribution is named after him. Education and career Weibull joined the Swedish Coast Guard in 1905 as a midshipman. He moved up the ranks with promotion to sublieutenant in 1907, Captain in 1916 and Major in 1940. While in the coast guard he took courses at the Royal Institute of Technology. In 1924 he graduated and became a full professor. He obtained his doctorate from the University of Uppsala in 1932. He was employed in Swedish and German industry as a consulting engineer. In 1914, while on expeditions to the Mediterranean, the Caribbean and the Pacific Ocean on the research ship ''Albatross'', Weibull wrote his first paper on the propagation of explosive waves. He developed the technique of using explosive charges to determine the type of ocean bottom sediments and their thickness. The same technique is still used today ...
