Effect of jamming on the capacity of MIMO channels

摘要

In this work, we study a communication system consisting of a transmitter, a receiver, and a jammer. It is assumed that the transmitter and the jammer are equipped with multiple antennas, while receiver is equipped with single antenna. Different cases are investigated, depending on the availability of Channel State Information (CSI) for the transmitter and/or the jammer. For each case, we propose the best strategy for the jammer, and for the transmitter by focusing on the er-godic capacity between the transmitter and the receiver, and derive an analytical expression for it.
