Detection and mitigation of jamming attacks in massive MIMO systems using random matrix theory

Consider the uplink of a single-cell multiuser MIMO system with a very large number of antennas, M, at the base station (BS) and K single-antenna users. A jamming device equipped with KJ antennas transmitting signals attempts to degrade the transmission between the users and the BS. In this paper, we propose a detection algorithm of the jamming attack as well as a method for its rejection. The proposed results are based on the application of results from random matrix theory. We assume that K and KJ are fixed as M converges to infinity while the coherence interval τ is assumed to be of the same order of magnitude as M.
