Figure 6From: Using information theoretic distance measures for solving the permutation problem of blind source separation of speech signalsConstructed signals for demonstration. (a) Signal U1(τ) is a speech signal at the frequency f = 3, 219.2 Hz, (b) U2(τ) is the same signal as U1(τ) but time delayed and (c) signal U3(τ) contains amplitudes of the same speech signal as U1(τ) at the frequency f = 3, 230 Hz (the next frequency bin) with an additional Gaussian noise.Back to article page
