Struct LinearPrecoder 

pub struct LinearPrecoder {
    pub w: CMat,
}

A linear precoder $x = W s$ (one column of the streams at a time).

Fields

w: CMat

The precoding matrix, $n_{t} \times$ streams.

Implementations

impl LinearPrecoder

pub fn zero_forcing( h: &ArrayView2<'_, C64>, total_power: f64, ) -> Result<LinearPrecoder>

Zero forcing for the users of the rows of h, scaled to total_power.

Errors

Error::Config if there are more users than transmit antennas, Error::Numerical for a rank-deficient channel.

pub fn regularized( h: &ArrayView2<'_, C64>, alpha: f64, total_power: f64, ) -> Result<LinearPrecoder>

Regularised zero forcing $H^{H}(H H^{H} + \alpha I)^{-1}$, scaled to total_power (use $\alpha = K \sigma^{2} / P$).

Errors

Error::Config for a negative alpha or a non-positive power, Error::Numerical for a singular system.
