What is Rayleigh fading and its solution?
Rayleigh fading is viewed as a reasonable model for tropospheric and ionospheric signal propagation as well as the effect of heavily built-up urban environments on radio signals. Rayleigh fading is most applicable when there is no dominant propagation along a line of sight between the transmitter and receiver.
What is meant by Rayleigh fading channel?
Rayleigh and Rician fading channels are useful models of real-world phenomena in wireless communications. These phenomena include multipath scattering effects, time dispersion, and Doppler shifts that arise from relative motion between the transmitter and receiver.
What causes Rayleigh fading?
Rayleigh fading is caused by multipath reception. The mobile antenna receives a large number, say N, reflected and scattered waves. Because of wave cancellation effects, the instantaneous received power seen by a moving antenna becomes a random variable, dependent on the location of the antenna.
How do you calculate channel coefficient?
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 Py=E|y|2=|h|2⋅Px.
