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.

RF receivers amplify signals and shift them to lower frequencies.
A mixer transfers local oscillator (LO) phase noise directly to its output.
Most RF receivers in modern communications or radar systems feed signals to an analog-to-digital converter (ADC).
This example shows how to use the RF Blockset™ Circuit Envelope library to simulate noise and calculate noise power.
This example shows how to use the RF Blockset™ Circuit Envelope library to measure the effect of thermal noise on the bit error rate (BER) of a communications system and to verify the result by comparing to a Communications System Toolbox™ reference model.
