WebBecause there is no direct ray component, Rayleigh fading is often classified as the worst case fading type. Using a one ray model, this small scale distribution simulates the … WebWhen the bandwidth is too small for the signal to resolve the individual components, the frequency response is approximately flat because of the minimal time dispersion caused by the multipath channel. This kind of multipath fading is often referred to as narrowband fading, or frequency-flat fading.

WebSep 8, 2024 · 1. In your definition of the SINR, h is the channel coefficient. What it means is this: if we send a signal x ( t) and model our channel as stationary and frequency-flat then the signal we receive is y ( t) = h ⋅ x ( t) (plus noise) so that its power is P y = E { y 2 } = h 2 ⋅ P x. This is why h 2 appears in your SINR expression ...
