Detailed Description

A model for the error rate for different modulations.

Doxygen introspection did not find any typical Config paths.

For OFDM modulation, the model description and validation can be found in http://www.nsnam.org/~pei/80211ofdm.pdf. For DSSS modulations (802.11b), the model uses the DsssErrorRateModel.

No Attributes are defined for this type.
No TraceSources are defined for this type.

		double	snr,
		uint32_t	nbits
	)		const

virtual

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

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

A chuck 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.

Parameters
