White Noise generator same signal every time I run the simulation

1 view (last 30 days)
Hi I am trying to add the White Noise to my sensor using the band limited white noise Block in simulink expecting to get a different noise to my signal but I am getting the same noise signal every time I run the simulation. the noise should be totally random every time I run it to simulate the noise we getting from the sensor.
anyone knows how to get this random noise every time?

Jurt use the rand function & add to the original signal data
signalData=
noiseData=rand(1,length(signalData));
signalNoise=signalData+noiseData;
However, if you are using real-time sensor data as noisy data, the case may be different.
