Fig. 3

Estimated probability density function for receiver correlation (p=2, Q=0) and different N. Noise correlation factor \(\varrho _{\text {max}}^{\eta }=0.05\). 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 {−10,−11,…,−15} dB
