WebAug 14, 2024 · In my opinion, no matter it's complex signal or real signal, the SNR equals to the input signal power, S, divided by the noise power, N. The difference is, for complex signal, S = Si + Sq, (Si = Sq, no consideration of IQ imbalance) and for real signal, S = Si or S = Sq Then, no matter it's complex or real, Es = S*Tsym and, N0 = N*Tsamp So, WebOct 27, 2012 · Matlab randn generates realisations from a normal distribution with zero mean and a standard deviation of 1. Samples from any other normal distribution can simply be generated via: numSamples = 1000; mu = 2; sigma = 4; samples = mu + sigma.*randn (numSamples, 1); You can verify this by plotting the histogram: figure;hist (samples (:));
