Struct ldpc_toolbox::simulation::modulation::Psk8Demodulator

pub struct Psk8Demodulator { /* private fields */ }

8PSK demodulator.

Assumes the same mapping as the Psk8Modulator. Demodulates symbols into LLRs using the exact formula implemented with the max-* function.

Implementations

impl Psk8Demodulator

pub fn new(noise_sigma: f64) -> Psk8Demodulator

Creates a new 8PSK demodulator.

The noise_sigma indicates the channel noise standard deviation. The channel noise is assumed to be a circularly symmetric Gaussian with mean zero and standard deviation noise_sigma in its real part and imaginary part (the total variance is 2 * noise_sigma * noise_sigma.
