Noise (Communications)

Fading:

• Fast Fading
• Slow Fading
• Rayleigh Fading
• Path Loss

Additive White Gaussian Noise (AWGN):

Formula:

$$\begin{array}{c}f(x)=\frac{1}{\sigma \sqrt{2\pi }}{e}^{\frac{1}{2}(\frac{x-\mu }{\sigma })}\\ \text{Where : }\mu =\text{DC}\text{ voltage}\\ \sigma =\text{Standard Deviation}\\ \\ \therefore f(x)=\frac{1}{\sigma \sqrt{2\pi }}{e}^{\frac{1}{2}(\frac{x-DC}{\sigma })}\end{array}$$

Extra:

Hata Model (for 150-1500MHz)
