Struct SignalModulation 

pub struct SignalModulation { /* private fields */ }

Navigation modulation model used by spectrum-domain metrics.

Implementations

impl SignalModulation

pub fn bpsk(order: f64) -> Result<Self, SignalAnalysisError>

Construct BPSK(n), with code rate n * 1.023 MHz.

pub fn bpsk1() -> Self

Construct BPSK(1), the GPS C/A spectral shape for long random codes.

pub fn boc( m: f64, n: f64, phasing: BocPhasing, ) -> Result<Self, SignalAnalysisError>

Construct BOC(m,n) with the requested square-wave phasing.

pub fn boc_sine(m: f64, n: f64) -> Result<Self, SignalAnalysisError>

Construct sine-phased BOC(m,n).

pub fn boc_cosine(m: f64, n: f64) -> Result<Self, SignalAnalysisError>

Construct cosine-phased BOC(m,n).

pub fn mboc_6_1_1_over_11() -> Self

Construct the normalized MBOC(6,1,1/11) PSD.

pub fn tmboc_6_1_4_over_33() -> Self

Construct the GPS L1C pilot TMBOC(6,1,4/33) PSD.

pub fn cboc_6_1_1_over_11(sign: CbocSign) -> Self

Construct one Galileo E1 CBOC(6,1,1/11) chip pulse.

pub fn weighted( components: Vec<WeightedComponent>, ) -> Result<Self, SignalAnalysisError>

Construct a custom normalized weighted PSD composite.

The component weights must be finite, non-negative, and sum to 1 within 1e-12. The resulting PSD is the weighted sum of the component PSDs, so it models time multiplexing or an explicitly published average spectrum rather than an arbitrary coherent channel sum.

pub fn psd_hz(&self, offset_hz: f64) -> Result<f64, SignalAnalysisError>

Return the normalized power spectral density at offset frequency f.

The return value has units of 1/Hz and integrates to unit power over infinite bandwidth for every shipped modulation.

pub fn code_rate_hz(&self) -> Result<f64, SignalAnalysisError>

Return the code rate in hertz when the modulation has one unambiguous rate.

pub fn label(&self) -> &'static str

Return a short stable label for the modulation.

Trait Implementations

impl Clone for SignalModulation

fn clone(&self) -> SignalModulation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SignalModulation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SignalModulation

fn eq(&self, other: &SignalModulation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
