Member Function Documentation

size_t ns3::PLC_InformationRatePhy::GetOfdmSymbolsPerCodeBlock

(

void

)

Returns:

Modulation symbols needed to map one code block

void ns3::PLC_InformationRatePhy::SetHeaderModulationAndCodingScheme

(

ModulationAndCodingType

mcs

)

A second fixed rate modulation and coding scheme has to be defined for the transmission of control frames and frame header. Only the payload of data frames can be encoded rateless. The robustness of control frame and frame header transmission can be increased by choosing a lower mcs

void ns3::PLC_InformationRatePhy::SetOfdmSymbolsPerCodeBlock

(

size_t

spb

)

[static]

Define number of modulation symbols needed to map one code block

Parameters:

spb

void ns3::PLC_InformationRatePhy::SetRatelessCodingOverhead

(

double

overhead

)

[static]

Define the minimal overhead induced by rateless encoding. default: 0.2

TODO: non static estimation with respect to message length and claimed decoding propability

Parameters:

overhead

(1 = 100%)
