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.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Known subclasses

Name	Type	Description
Ieee80211DimensionalReceiver	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.
Ieee80211ScalarReceiver	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.
Ieee80211UnitDiskReceiver	compound module	See also: Ieee80211UnitDiskTransmitter, Ieee80211UnitDiskRadio, UnitDiskRadioMedium.

Extends

Name	Type	Description
NarrowbandReceiverBase	compound module	This module servces as a base module for narrowband receiver models.

Parameters

Name	Type	Default value	Description
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	"BPSK"	one of "BPSK", "16-QAM", "256-QAM"
opMode	string
bandName	string
channelNumber	int
