Known subclasses

Name	Type	Description
APSKDimensionalReceiver	compound module	This receiver model receives a transmission succesfully if the minimum of the signal to noise and interference ratio over the duration of the reception is sufficiently high. It uses the error model to compute the error rate based on this value and the used modulation.
APSKScalarReceiver	compound module	This receiver model receives a transmission succesfully if the minimum of the signal to noise and interference ratio over the duration of the reception is sufficiently high. It uses the error model to compute the error rate based on this value and the used modulation.
Ieee80211ReceiverBase	compound module	This receiver model serves as the base module for IEEE 802.11 receivers. It supports switching channels, configuring different operation modes, and preamble modes.
Ieee802154NarrowbandScalarReceiver	compound module	(no description)

Parameters

Name	Type	Default value	Description
energyDetection	double		no signal is detected at all below this reception power threshold (idle state)
sensitivity	double		reception is not possible if the signal power is below sensitivity (idle or busy states)
snirThreshold	double		reception is not successful if the SNIR is below this threshold (unsuccessful reception)
carrierFrequency	double		center frequency of the band where this receiver listens on the medium
bandwidth	double		bandwidth of the band where this receiver listens on the medium
errorModelType	string		NED type of the error model
modulation	string		one of "BPSK", "16-QAM", "256-QAM"
