Struct EffectiveChannel 

pub struct EffectiveChannel { /* private fields */ }

The effective delay–Doppler channel of Otfs::effective_channel: an $MN \times MN$ matrix of $P$ entries per row, one per path (the entries of paths that land on the same column add up).

Implementations

impl EffectiveChannel

pub fn size(&self) -> usize

The size $MN$ of the square matrix.

pub fn n_paths(&self) -> usize

The number $P$ of entries per row (the paths).

pub fn row(&self, p: usize) -> impl Iterator<Item = (usize, C64)> + '_

The entries (column, value) of row p, one per path.

Panics

If p is not below EffectiveChannel::size.

pub fn apply(&self, x: &[C64]) -> Result<Vec<C64>>

$\mathbf{y} = H_{\mathrm{eff}} \mathbf{x}$, in $O(MNP)$ operations.

Errors

Error::Shape unless x has $MN$ values.

pub fn to_dense(&self) -> CMat

The dense $MN \times MN$ matrix ($16 (MN)^{2}$ bytes: 16 MB at $32 \times 32$), for the detectors that take a matrix.
