Struct MessagePassing 

pub struct MessagePassing {
    pub prior: Prior,
    pub domain: Domain,
    pub iterations: usize,
}

The configuration shared by lama, oamp and their state evolutions: the prior of every entry of $x$, the domain of the model and the number of iterations.

Examples

use comnum_mimo::message_passing::{Domain, MessagePassing, Prior, amp_state_evolution};
use comnum_mapping::constellation::Constellation;
let qpsk = Prior::uniform(&Constellation::qam(4)?.normalized());
let config = MessagePassing { prior: qpsk, iterations: 30, ..MessagePassing::default() };
config.check()?;
let se = amp_state_evolution(&config, 0.5, 0.05);
assert_eq!(se.len(), 30);

Fields

prior: Prior

The prior of every entry of $x$.

domain: Domain

The domain of the symbols, the channel and the noise.

iterations: usize

Iterations (at least 1 for the detectors).

Implementations

impl MessagePassing

pub fn check(&self) -> Result<()>

Check the configuration.

Errors

Error::Config for zero iterations or a sparsity outside $(0, 1]$; Error::Shape for a discrete prior without points or with one probability per point missing.

Trait Implementations

impl Clone for MessagePassing

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessagePassing

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MessagePassing

fn default() -> MessagePassing

A Gaussian prior of unit variance (Prior::BernoulliGaussian with $\rho = 1$), complex, 10 iterations.

impl PartialEq for MessagePassing

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
