Detailed Description

Set of frequency values implementing the domain of the functions in the Function Space defined by SpectrumValue.

Frequency values are in Hz. It is intended that frequency values are non-negative, though this is not enforced.

Constructor & Destructor Documentation

◆ SpectrumModel() [1/3]

ns3::SpectrumModel::SpectrumModel ( const std::vector< double > &  centerFreqs)

This constructs a SpectrumModel based on a given set of frequencies, which is assumed to be sorted by increasing frequency.

The lower (resp. upper) frequency band limit is determined as the mean value between the center frequency of the considered band and the center frequency of the adjacent lower (resp. upper) band.

Parameters
centerFreqsthe vector of center frequencies.

Definition at line 42 of file spectrum-model.cc.

◆ SpectrumModel() [2/3]

ns3::SpectrumModel::SpectrumModel ( const Bands bands)

This constructs a SpectrumModel based on the explicit values of center frequencies and boundaries of each subband.

Parameters
bandsthe vector of bands for this model

Definition at line 72 of file spectrum-model.cc.

References m_bands, m_uid, m_uidCount, and NS_LOG_INFO.

◆ SpectrumModel() [3/3]

ns3::SpectrumModel::SpectrumModel ( Bands &&  bands)

This constructs a SpectrumModel based on the explicit values of center frequencies and boundaries of each subband.

This is used if bands is an rvalue.

Parameters
bandsthe vector of bands for this model

Definition at line 79 of file spectrum-model.cc.
