hello i would like to ask how to create a random signals booster using matlab and simulink. it works similar to a 5g wifi booster but with random signals. thanks very much.

Hi,
I understand you would like to generate a random signal and boost it with a boost factor. You can achieve this in "Matlab" using "randn" function. Here is an example to demonstrate how you can accomplish this:
fs = 1e3; % Sampling frequency (Hz)
t = 0:1/fs:1-1/fs; % Time vector
randomSignal = randn(size(t)) % Generate Gaussian noise
randomSignal = 1×1000
-1.3482 -0.3966 0.3447 -0.0224 0.0609 0.3367 0.3766 0.6757 -0.7913 0.1445 -0.3929 -0.3885 -1.4137 1.0384 0.6089 1.6174 0.7861 0.0964 0.1965 -2.1773 0.1968 -1.2690 0.7163 -0.2982 0.6974 0.2624 -2.3251 -0.5552 0.6236 -1.3616
% Define the gain (Amplification factor)
gain = 10; % Boost factor
% Boost the signal
boostedSignal = gain * randomSignal
boostedSignal = 1×1000
-13.4817 -3.9664 3.4468 -0.2240 0.6090 3.3674 3.7663 6.7570 -7.9130 1.4448 -3.9292 -3.8853 -14.1373 10.3838 6.0893 16.1742 7.8608 0.9644 1.9653 -21.7729 1.9676 -12.6897 7.1630 -2.9821 6.9736 2.6238 -23.2511 -5.5519 6.2360 -13.6156
Alternatively, you can achieve this using the "Random Source" block to generate random signal and "Gain" block to amplify the signal.
I hope this helps!
