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.
|Amplifier||Model amplifier in RF systems|
|Attenuator||Model attenuator for RF circuit|
|Resistor||Model resistor for circuit envelope analysis|
|S-Parameters||Model S-parameter network|
|Mixer||Model mixer in RF systems|
|Variable Attenuator||Model variable attenuator|
|Variable Phase Shift||Model variable phase device|
|Variable Capacitor||Model variable capacitor|
|Variable Inductor||Model variable inductor|
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 SimRF™ Circuit Envelope library to simulate noise and calculate noise power.
This example shows how to use the SimRF™ Circuit Envelope library to measure the effect of noise figure on bit error rate (BER) of a SimRF RF receiver model and to verify the result by comparing to a Communications System Toolbox™ reference model.
