Explain rayleigh fading

Web2. Time Selective Fading: If the fading changes relatively quickly (compared to the duration of a data bit) then the fading is said to be time selective. 3. Doubly Selective: If both are true then it is said to be doubly selective. X-3 Fading Channel Models (cont.) Consider a simple model for fading where there are a finite number of paths ...
