Member Function Documentation

◆ CalcPer()

double ns3::UanPhyPerUmodem::CalcPer	(	Ptr< Packet >	pkt,
		double	sinrDb,
		UanTxMode	mode )

overridevirtual

Calculate the packet error probability based on SINR at the receiver and a tx mode.

This implementation uses calculations for binary FSK modulation coded by a rate 1/2 convolutional code with constraint length = 9 and a viterbi decoder and finally a CRC capable of correcting one bit error. These equations can be found in the book, Digital Communications, by Proakis (any version I think).

Parameters

pkt	Packet which is under consideration.
sinrDb	SINR at receiver.
mode	TX mode used to transmit packet.

Returns: Probability of packet error.

Implements ns3::UanPhyPer.
