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.
Model System Noise Figure
RF receivers amplify signals and shift them to lower frequencies.
Design Receiver with ADC
Design RF Receiver using ADC.
Noise in RF Systems
Noise factor, noise figure, noise floor, thermal noise power, noise
temperature, white noise, colored noise.
Use the RF Blockset™ Circuit Envelope library to simulate noise and calculate noise power. Results are compared against theoretical calculations and a Communications Toolbox™ reference model.
Model and visualize LO phase noise. A mixer transfers local oscillator (LO) phase noise directly to its output.
A test bench model to describe the noise introduced by a 2-port device.
Use the Noise block to calculate the classic thermal noise floor, kT, for a matched resistor circuit. Model configuration is as follows: Time step of the model is 1e-6 and frequency is 2 GHz.
Use RF Blockset to measure the Gain and Noise Figure of an RF system over a given spectral range.
