Estimated probability density function for time correlation (p=1, Q=4) and different N. Solid lines represent the histograms, while dashed lines depict the means. The \(\mathcal {H}_{0}\) case result is shown in black, while the \(\mathcal {H}_{1}\) case results are colored, where the SNR from right to left is given by {−6,−7,…,−10} dB.
