Noise Modeling
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
Topics
- 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.
Featured Examples
RF Noise Modeling
Simulate noise and calculate noise power.
Model LO Phase Noise
Model and visualize LO phase noise. A mixer transfers local oscillator (LO) phase noise directly to its output.
Spot Noise Data in Amplifiers and Effects on Measured Noise Figure
A test bench model to describe the noise introduced by a 2-port device.
Explicitly Simulate Resistor Thermal Noise
Use the Noise block to calculate the classic thermal noise floor, kT, for a matched resistor circuit. Model configuration is as follows:
Measurement of Gain and Noise Figure Spectrum
Use RF Blockset™ to measure the Gain and Noise Figure of an RF system over a given spectral range.
