Confidential Broadcasting via Linear Precoding in Non-Homogeneous MIMO Multiuser Networks

We propose linear precoding with power control to achieve confidential broadcasting in multi-input-multi-output multiuser networks such that the base station (BS) with Nt antennas securely broadcasts messages to K users with Nr antennas each. We focus on the practical non-homogeneous scenario where the distances between the BS and the users are not equal… CONTINUE READING
