Detailed Description

Link results for forward link.

The instance will be SatLinkResultsDvbS2 or SatLinkResultsDvbS2X.

Loads and maintains multiple SatLookUpTable. Provides query service based on modulation and coding scheme.

See usage examples in the parent class documentation (SatLinkResults).

Definition at line 352 of file satellite-link-results.h.

Constructor & Destructor Documentation

◆ SatLinkResultsFwd()

ns3::SatLinkResultsFwd::SatLinkResultsFwd ( )

Default constructor.

Definition at line 222 of file satellite-link-results.cc.

◆ ~SatLinkResultsFwd()

ns3::SatLinkResultsFwd::~SatLinkResultsFwd ( )

inline

Definition at line 360 of file satellite-link-results.h.

Member Function Documentation

◆ DoInitialize()

virtual void ns3::SatLinkResultsFwd::DoInitialize ( )

protectedpure virtual

Initialize look up tables.

Child classes must implement this function to initialize m_table member variable. This is typically done by loading pre-defined input files from the file system. In case of failure, the function should throw an error by calling NS_FATAL_ERROR.

Implements ns3::SatLinkResults.

Implemented in ns3::SatLinkResultsDvbS2X, and ns3::SatLinkResultsDvbS2.

◆ GetBler()

double ns3::SatLinkResultsFwd::GetBler	(	SatEnums::SatModcod_t	modcod,
		SatEnums::SatBbFrameType_t	frameType,
		double	esNoDb
	)		const

Get a BLER value from link results.

Parameters

modcod	Modulation and coding scheme
frameType	BB frame type (short, long)
esNoDb	the received Es/No in dB

Returns: BLER value, which is a double ranging between [0..1]

Must be run after SatLinkResults::Initialize is called.

Short BB frame is assumed to be requiring m_shortFrameOffsetInDb dB higher Es/No if compared to normal BB frame. TODO: Proper link results need to be added for short BB frame in FWD link.

Definition at line 244 of file satellite-link-results.cc.

References ns3::SatLinkResults::m_isInitialized, m_shortFrameOffsetInDb, m_table, and ns3::SatEnums::SHORT_FRAME.

◆ GetEsNoDb()

double ns3::SatLinkResultsFwd::GetEsNoDb	(	SatEnums::SatModcod_t	modcod,
		SatEnums::SatBbFrameType_t	frameType,
		double	blerTarget
	)		const

Get a Es/No requirement for a given BLER target from link results.

Parameters

modcod	Modulation and coding scheme
frameType	BB frame type (short, long)
blerTarget	Target BLER for the system

Returns: Es/No value

Must be run after SatLinkResults::Initialize is called.

Short BB frame is assumed to be requiring "m_shortFrameOffsetInDb" dB higher Es/No if compared to normal BB frame. TODO: Proper link results need to be added for short BB frame in FWD link.

Definition at line 269 of file satellite-link-results.cc.

References ns3::SatLinkResults::m_isInitialized, m_shortFrameOffsetInDb, m_table, and ns3::SatEnums::SHORT_FRAME.

◆ GetTypeId()

TypeId ns3::SatLinkResultsFwd::GetTypeId ( void )

static

Get the type ID.

Returns: the object TypeId

Definition at line 230 of file satellite-link-results.cc.
