◆ CalculateSnr()

double ns3::ErrorRateModel::CalculateSnr	(	WifiTxVector	txVector,
		double	ber
	)		const

Parameters

txVector	a specific transmission vector including WifiMode
ber	a target ber

Returns: the snr which corresponds to the requested ber

◆ GetChunkSuccessRate()

virtual double ns3::ErrorRateModel::GetChunkSuccessRate	(	WifiMode	mode,
		WifiTxVector	txVector,
		double	snr,
		uint64_t	nbits
	)		const

pure virtual

A pure virtual method that must be implemented in the subclass.

This method returns the probability that the given 'chunk' of the packet will be successfully received by the PHY.

A chunk can be viewed as a part of a packet with equal SNR. The probability of successfully receiving the chunk depends on the mode, the SNR, and the size of the chunk.

Note that both a WifiMode and a WifiTxVector (which contains a WifiMode) are passed into this method. The WifiTxVector may be from a signal that contains multiple modes (e.g. PLCP header sent differently from PLCP payload). Consequently, the mode parameter is what the method uses to calculate the chunk error rate, and the txVector is used for other information as needed.
