Fig. 13From: Leveraging discrete modulation and liquid metal antennas for interference reductionCapacity for antenna states. For different liquid metal states that satisfy \(h_{1}^{2}<h_{2}^{2}<h_{1}^{4}\frac{P}{N}\), we plot the capacity with Gaussian inputs ‘\(-\square -\) and the achievable sum rate (via the lower bound in Proposition 1) using discrete PAM inputs ‘\(-\circ\)’Back to article page
