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
