Matlab program for signal averaging to improve the SNR?

Answer 1

To improve the signal-to-noise ratio (SNR) using signal averaging in MATLAB, you can employ the following steps. First, collect multiple samples of the noisy signal in a matrix format, where each row represents a different instance of the signal. Then, compute the average across these samples using the mean function. This approach reduces noise while retaining the underlying signal, effectively enhancing the SNR. Here's a simple code snippet to illustrate this:

num_samples = 100; % Number of signal instances
signal = randn(num_samples, 1000); % Simulated noisy signals
averaged_signal = mean(signal, 1); % Average across samples
