Coordinated beamforming for cognitive multi-cell networks with wiretap channels

Show other versions (1)

Owing to the coupling among the vectors to be optimized，the problem becomes non-convex and non-linear.Accordingly，a centralized coordinated beamforming design method was proposed by constraining the leakage interference and using the semi-definite relaxation，and on the base of it，a decentralized alg...
