NarrowbandReceiverBase¶

Package: inet.physicallayer.wireless.common.base.packetlevel

compound module NarrowbandReceiverBase

Serves as a base module for narrowband receiver models.

Usage diagram¶

Inheritance diagram¶

Known subclasses¶

Name	Type	Description
ApskReceiver	compound module	This receiver model receives a transmission successfully 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.
Ieee80211Receiver	compound module	This receiver model receives an IEEE 802.11 transmission successfully if the minimum of the signal to noise and interference ratio over the duration of the reception is sufficiently high. It uses one of the IEEE 802.11 specific error models to compute the error rate based on this value and the used operation mode.
Ieee802154NarrowbandReceiver	compound module	(no description)

Extends¶

Name	Type	Description
SnirReceiverBase	compound module	Serves as a base module for SNIR receiver models.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
ignoreInterference	bool	false	True means interfering transmissions are ignored when determining whether a reception is successful or not
signalAnalogRepresentation	string	“scalar”
snirThreshold	double		Reception is not successful if the SNIR is below this threshold (unsuccessful reception)
snirThresholdMode	string	“min”
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)
centerFrequency	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
modulation	string		One of “BPSK”, “16-QAM”, “256-QAM”
