Fig. 10From: Secure massive MIMO system with two-way relay cooperative transmission in 6G networksSecrecy sum-rate in different \(p_{\max }\) and \(L\) with \(p_{BS} = 35{\text{dBm}}\), \(p_{u} = 30{\text{dBm}}\), and \(K = \{ 1,10\}\). Blue line: \(K = 1, \, L = 20\); green line: \(K = 1, \, L = 10\); yellow line: \(K = 1, \, L = 5\); pink line: \(K = 10, \, L = 20\); black line: \(K = 10, \, L = 10\); purple line: \(K = 10, \, L = 5\)Back to article page
