Fig. 3From: Leveraging discrete modulation and liquid metal antennas for interference reductionMinimum distance. Minimum distance of sum of two PAM signals with \(n=10\) as a function of \(h_2\) with \(h_{1}=1\). \(d_{{\mathrm{min}} }\left( {\widetilde{X}}_{d}\right)\) is plotted by calculating the smallest distance in the sum constellation \(\sqrt{h_{1}^{2}P}X_{1}+\sqrt{h_{2}^{2}P}X_{2}\) with \(X_{1},X_{2}\) generated as n-PAM inputsBack to article page
