Enum Prototype 

#[non_exhaustive]
pub enum Prototype {
    Phydyas,
    Hermite,
}

The prototype filter of an Fbmc.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Phydyas

The PHYDYAS filter of Bellanger (overlapping factors 2, 3 and 4).

Hermite

The Hermite pulse of Haas & Belfiore (any overlapping factor, the truncation length; Nissel et al. 2017 take 8).

Implementations

impl Prototype

pub fn taps(self, subcarriers: usize, overlap: usize) -> Result<Vec<f64>>

The $KM - 1$ taps of unit energy for subcarriers $M$ and overlapping factor overlap $K$.

Errors

Error::Config for an overlapping factor the prototype does not define.

pub fn localisation( self, subcarriers: usize, overlap: usize, ) -> Result<(f64, f64)>

The time and frequency localisation of the prototype, $(\sigma_{t}/T_{0},
\sigma_{f} T_{0})$, $\sigma_{t}^{2} = \int (t - \bar t)^{2} |p(t)|^{2} dt$, $\sigma_{f}^{2} = \int (f - \bar f)^{2} |P(f)|^{2} df$ for a pulse of unit energy (Nissel, Schwarz & Rupp 2017, eqs. (4)–(5)), from the Prototype::taps for subcarriers $M = T_{0}$ and overlap, the spectrum by a DFT zero-padded 16 times over; the bound is $\sigma_{t}\sigma_{f} \ge 1/(4\pi)$ (the Gaussian).

Errors

As Prototype::taps.
