random noise) noise_segment = randn(size(t)) * 0.1; % Simulated noise % Calculate SNR using MATLAB's built-in function SNR_value = snr(signal, noise_segment); % Alternatively, calculate manually power_signal = rssq(signal(:))^2; ...
Hello. Suppose that I have a sensor connected to my unmanned air vehicle, that measures the height of the each point it sees on the surface. The sensor measures with %1 error, such as adding random noise to the actual height value. How can I generate such a data, say 500 values each...

Hi all, I have got a question regarding noise removal. I am doing a sensor project, and I need to measure output signal from the sensors. Theoretically speaking, output signal should be sine wave.However, sensor itself has got sine-wave-like noise. Therefore the supercomposition of two wave...
and how to simulate sine wave and sin wave+ noise in modelsim altera --- Quote End --- shift register based prbs can generate pseudo random noise. LUTs also can be used to store whatever type of noise you get from tools like matlab e.g. gaussian. You add noise signal to your...
i want to add noise(awgn) of 20 db to input signal and the resultant would be desired signal of the adaptive filter and also i want to normalize the power to 1 db...can someone tell me how to do this in matlab thanks 2 件のコメント ...
