Abstract:

In this paper, we study the optimal transmitter beamforming design in a coordinated multicell multicast network under the wiretap channel model, where each cell serves a group of users and a single-antenna eavesdropper tries to overhear the confidential information. We study the problem of finding the optimal beamforming strategy at each base station to minimize the total transmit power of the multicell network while guaranteeing secrecy and QoS requirements of each user. The resulting non-convex optimization problem is solved through a sequence of convex semi-definite relaxations. The effectiveness of the proposed algorithm is validated via numerical simulations.
