Detailed Description

Implementation for a single path Stationary Jakes propagation loss model.

The Jakes propagation loss model implemented here is described in [1].

We consider one transmitter - receiver pair and calculate the complex coefficients for this case as follow:

\[ X(t)=X_c(t) + j X_s(t)\]

\[ X_c(t) = \frac{2}{\sqrt{M}}\sum_{n=1}^{M}\cos(\psi_n)\cos(\omega_d t\cos(\alpha_n)+\phi_n)\]

\[ X_s(t) = \frac{2}{\sqrt{M}}\sum_{n=1}^{M}\sin(\psi_n)\cos(\omega_d t\cos(\alpha_n)+\phi_n)\]

with

\[ \alpha_n = \frac{2\pi n - \pi + \theta}{4M}, n=1,2, \ldots,M\]

where $\theta$, $\phi$, and $\psi_n$ are statically independent and uniformly distributed over $[-\pi, \pi)$ for all $n$.
