Struct Eigenmode 

pub struct Eigenmode {
    pub precoder: CMat,
    pub combiner: CMat,
    pub gains: Vec<f64>,
    pub powers: Vec<f64>,
}

Eigenmode (SVD) transmission: precoder $V P^{1/2}$ and receive filter $U^{H}$.

Fields

precoder: CMat

Precoder, $n_{t} \times$ active streams.

combiner: CMat

Receive filter, active streams $\times n_{r}$.

gains: Vec<f64>

Singular values of the active modes.

powers: Vec<f64>

Power of every active mode.

Implementations

impl Eigenmode

pub fn new( h: &ArrayView2<'_, C64>, total_power: f64, noise_var: f64, water_filling: bool, ) -> Result<Eigenmode>

The modes of h with water-filling of total_power against the receiver noise variance noise_var (equal power on every non-zero mode if water_filling is false); modes without power are dropped.

Errors

As water_filling_powers, and Error::Config for a non-positive noise variance or a zero channel.

pub fn n_streams(&self) -> usize

Number of active streams.
