rician fading model

Fading model for narrowband fading channel gain.

Here, there is a dominant line of sight path.

Recall that the channel being studied is of the form

β(t)=α0(t)ejϕ0(t)+Nn=1αn(t)ejϕn(t)

The first part is complex gaussian, but the sum follows the rayleigh fading model.

We know the variance (power) of the rayleigh part is 2σ2, this is the expected power of the sum of all the NLOS parts of the channel.

The variance (power) of the line of sight channel component is s2

The Rician K-factor is s2/(2σ2).
