Fig. 7From: Secure massive MIMO system with two-way relay cooperative transmission in 6G networksSecrecy sum-rate in different \(p_{u}\) and \(p_{BS}\) with \(p_{\max } = 30\,{\text{dBm}}\) and \(K = 1\). Blue line: \(p_{BS} = 10\,{\text{dBm}}\); green line: \(p_{BS} = 5\,{\text{dBm}}\); yellow line: \(p_{BS} = 3\,{\text{dBm}}\); pink line: \(p_{BS} = 0\,{\text{dBm}}\)Back to article page
