I am asking about Rician K- Factor in this model:

http://web.stanford.edu/group/introstwc/Course%20Notes/lect3.pdf

I know that if $K=0$ then it is a pure Rayleigh fading, if $K= \infty$, then non fading Channel.

What is it, if $0<K<\infty$ ?

If i represet the NLOS component using the Kronecker model and take expected value from $\mathbf{H}$, then I get only loscomponent. Will be it right?

    $\begingroup$ For $0 < K < \infty$, the channel is a combination of both a deterministic component (i.e., LOS) and a fading component. As the $K$-factor is the ratio of the energy in the deterministic Line-of-Sight (LOS) component to the energy in the aggregation of the random scattered paths (i.e., the fading component), higher $K$ means that the channel is more deterministic. As for the 2nd part of your question, I'm not sure to understand what you meant. $\endgroup$

  • $\begingroup$ thanks. the second question: If i represet the NLOS component using the Kronecker model and take expected value from H, Did i get then only LOS-component? $\endgroup$

I have a question about Rician channel with L taps. The frequency selective Rician fading channels with delay spread of L = 6 taps are considered for both direct link and reflecting link, where the first tap is set as the deterministic line-of-sight (LoS) component and the remaining taps are non-LoS components following the Rayleigh fading distribution, with η being the ratio of the total power of non-LoS components to that of LoS component. Is this a correct matlab code for the above definition?

h = zeros(L, 1); 
h(1) = sqrt(eta/(1 + eta)); % LoS component 
h(2:end) = sqrt(1/(2*(1 + eta))) * (randn(L-1, 1) + 1i * randn(L-1, 1)); % Non-LoS components
