Rayleigh and rician distributions

WebMar 6, 2008 · Rayleigh and Rician slow fading channels are considered in this paper. The fading process can be obtained by considering the mean-square values of the signal and noise. The distribution and density functions are useful in defining the “fading margin” used to accommodate the expected amount of fading to maintain the Quality of Service (QoS) … WebAlphabit.

WebNov 22, 2024 · Impulse Noise. If b > a, intensity b will appear as a light dot in the image. Conversely, level a will appear like a black dot in the image. Hence, this presence of white and black dots in the image resembles to salt-and-pepper granules, hence also called salt-and-pepper noise. When either P a or P b is zero, it is called unipolar noise. WebChannel hardening effect: This refers to the phenomenon that in massive MIMO the norm of each channel vector from the same Rayleigh fading distribution converges to the same constant by the law of large numbers.
