NoiseTransmitter¶

Package: inet.physicallayer.wireless.noise

compound module NoiseTransmitter

Transmitter module that generates noise signals with configurable parameters. Creates noise transmissions with specified duration, center frequency, bandwidth, and power. Used by NoiseSource to produce interference in wireless networks for testing protocol robustness and simulating realistic channel conditions.

Used in compound modules¶

Name	Type	Description
NoiseSource	compound module	A network node that generates periodic noise transmissions that can interfere with wireless communications. Alternates between sleep and transmission states based on configurable intervals. Uses a NoiseTransmitter to create noise signals with specified duration, frequency, bandwidth, and power parameters. Useful for testing protocol robustness against interference in wireless networks.

Extends¶

Name	Type	Description
TransmitterBase	compound module	(no description)

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
