Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime), the amount of scattering is inver… Webthe probability that the system cannot successfully decode the transmitted symbols. Corresponding to this outage probability, there is a minimum received SNR, γmin, given by Pout = p(γ < γmin).
