Implemented by

Name	Type	Description
DimensionalBackgroundNoise	compound module	Background noise model for wireless communications that represents ambient noise as a power spectral density function of time and frequency. Supports configurable time-varying and frequency-varying gain patterns with various interpolation methods. Used to model realistic noise conditions in wireless channel simulations.
IsotropicDimensionalBackgroundNoise	compound module	This background noise model describes noise that does not change over space, time and frequency. It produces dimensional noise signals that can be further used in dimensional computations.
IsotropicScalarBackgroundNoise	compound module	This background noise model describes noise that does not change over space, time, and frequency. It produces scalar noise signals that can be further used in scalar computations.

Used in compound modules

Name	Type	Description
RadioMedium	compound module	The medium model describes the shared physical medium where communication takes place. It keeps track of radios, noise sources, ongoing transmissions, background noise, and other ongoing noises. The medium computes when, where and how transmissions and noises arrive at receivers. It also efficiently provides the set of interfering transmissions and noises for the receivers.
