Struct RandomDisc 

pub struct RandomDisc {
    pub radius: f64,
    pub alpha: f64,
}

Users dropped uniformly in a disc around the base station, path loss $1 + d^{\alpha}$, Rayleigh fading.

Fields

radius: f64

Radius $\mathcal{R}_{D}$ of the disc (m).

alpha: f64

Path-loss exponent $\alpha$.

Implementations

impl RandomDisc

pub fn gain_cdf(&self, y: f64) -> Result<f64>

The CDF of the gain $|h|^{2}$ of a user dropped at random, eq. (3) (Gauss–Legendre, 256 nodes on $[0, \mathcal{R}_{D}]$).

Errors

Error::Config for a radius or an exponent that is not positive and finite.

pub fn gain_cdf_chebyshev(&self, y: f64, n: usize) -> Result<f64>

The Gauss–Chebyshev approximation (4) of RandomDisc::gain_cdf with n nodes.

Errors

As RandomDisc::gain_cdf, and Error::Config for n = 0.

pub fn gain_slope(&self, n: usize) -> Result<f64>

The slope $\eta = \frac{1}{\mathcal{R}{D}}\sum{n}\beta_{n}$ of the approximate CDF at zero (eq. (10)) with n Gauss–Chebyshev nodes.

Errors

As RandomDisc::gain_cdf_chebyshev.
