Struct Dpsk 

pub struct Dpsk { /* private fields */ }

Differential M-PSK with Gray-labelled phase transitions: the differential phase index $k$ carries the label $g(k)$ (comnum_math::gray).

Implementations

impl Dpsk

pub fn new(m: usize) -> Result<Dpsk>

Differential PSK of order m.

Errors

Error::Config unless m is a power of two ≥ 2.

pub fn order(&self) -> usize

The order $M$.

pub fn bits_per_symbol(&self) -> usize

Bits per symbol, $\log_{2} M$.

pub fn indices(&self, bits: &[u8]) -> Result<Vec<usize>>

The differential phase indices of a bit stream (most significant bit first).

Errors

Error::Shape if the number of bits is not a multiple of $\log_{2} M$.

pub fn bits(&self, indices: &[usize]) -> Result<Vec<u8>>

The bits of a sequence of differential phase indices.

Errors

Error::Config if an index is not below $M$.

pub fn map_bits(&self, bits: &[u8]) -> Result<Vec<C64>>

The n/log2 M + 1 unit-energy PSK symbols carrying n bits (the reference first).

Errors

Error::Shape if the number of bits is not a multiple of $\log_{2} M$.

pub fn demap_bits(&self, r: &[C64]) -> Result<Vec<u8>>

Noncoherent demodulation (detect) of n + 1 received symbols into n log2 M bits.

Errors

Error::Shape for an empty input.

pub fn demodulate_coherent(&self, r: &[C64]) -> Result<Vec<u8>>

Coherent demodulation with differential decoding (detect_coherent then decode) of n + 1 received symbols into n log2 M bits.

Errors

Error::Shape for an empty input.
