Rayleigh

Lord, title of John William Strutt, 1842--1919, British physicist. He discovered argon (1894) with Ramsay and made important contributions to the theory of sound, the theory of scattering of radiation, etc. Nobel prize for physics 1904

rayleigh

[′rā·lē]
(optics)
A unit of brightness, used to measure the brightness of the night sky and aurorae, equal to 1010/4π quanta per square meter per second per steradian.

Furthermore, we also make the performance comparison of modulation schemes under Nakagami-m fading channel with other fading channels such as Rician and Rayleigh and show that the performance of the system is better in case of Nakagami-m fading channels as compared to other fading channels.
