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 ... WebDec 6, 2024 · Rayleigh fading ideally represents multi-path fading in wireless transmission as shown in the figure above.

WebWhen there is a dominant stationary (nonfading) signal component present, such as a line-of-sight propagation path, the small-scale fading envelope distribution is Ricean. In such a situation, random multipath components arriving at different angles are superimposed on a stationary dominant signal. 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. http://www.wu.ece.ufl.edu/books/EE/wireless/FadingChannel.html iosgods bypass hidden content
