Confidential broadcasting via coordinated beamforming in two-cell networks

He, Biao; Yang, Nan; Yuan, Jinhong; Zhou, Xiangyun


We design a linear precoder based on the principles of the generalized regularized channel inversion (RCI) precoder that achieves confidential broadcasting in a two-cell network. In each cell of the network, an N-antenna base station (BS) communicates with K single-antenna users. We consider coordinated beamforming where the BSs in the two cells do not share messages but the users in the two cells feed back their channel state information to both BSs. In the precoder design, we...[Show more]
