Noise Modeling

Noise sources, phase noise, thermal noise, noise figure specification

Use noise sources to simulate white or colored noise in RF models and calculate the noise power. To calculate thermal noise, use S-Parameters block.

Blocks

Amplifier	Model amplifier in RF systems
Resistor	Model resistor for circuit envelope analysis
Mixer	Model mixer in RF systems
IMT Mixer	Model mixer using intermodulation table (IMT)
S-Parameters	Model S-parameter network

Measures noise figure of system

Noise	Model noise using current or voltage noise source in RF systems
Continuous Wave	Model constant envelope source

Define system simulation settings

RF Noise and Nonlinearity Simulations
Simulate RF noise and nonlinearities.
Model System Noise Figure
This example shows how to model system noise figure in RF Blockset™.
Design Receiver with ADC
Most RF receivers in modern communications or radar systems feed signals to an analog-to-digital converter (ADC).
Noise in RF Systems
Noise factor, noise figure, noise floor, thermal noise power, noise temperature, white noise, colored noise.
