Secrecy Balancing over Two-User MISO Interference Channels with Rician Fading

Abstract EN

This paper considers a 2-user multiple-input single-output (MISO) interference channel with confidential messages (IFC-CM), in which the Rician channel model is assumed.

The coordinated beamforming vectors at the two transmitters have the similar parameterizations as those for perfect CSI, which could be optimized jointly and achieved by agreeing on the real parameters between the two users.

Our main contribution is that a quadratic relationship between the two real-valued parameters can be derived for the Rician channel to reach the ergodic secrecy rate balancing point.

Simulation results present the secrecy performance over the 2-user MISO IFC-CM scenario.
