In this paper, we analyze pilot contamination (PC) attacks on a multi-cell massive multiple-input multiple-output (MIMO) network with correlated pilots. We obtain correlated pilots using a user capacity-achieving pilot sequence design. This design relies on an algorithm which designs correlated pilot sequences based on signal-to-interference-plus-noise ratio (SINR) requirements for all the legitimate users. The pilot design is capable of achieving the SINR requirements for all users even in the… Expand
Mitigating the Interference Caused by Pilot Contamination in Multi-cell Massive Multiple Input Multiple Output Systems Using Low Density Parity Check Codes in Uplink Scenario
The simulated results have shown that the LDPC coded scheme performs better than the uncoded counterpart and the sum-rate capacity increases when the strength of channel coefficients between the BS antennas of the desired cell and the users of remaining cells is less. Expand
A new approach to mitigate pilot contamination in massive multiple-input multiple-output (MIMO) systems is proposed in this paper and a perfect agreement is found between theoretical and Monte Carlo simulation results which show that when the interfering user’s AoA is increased the pilot contamination level is significantly minimized, the desired users’ data path gain estimation error also minimized, and hence its data rate is significantly increased.

This paper presents and model the pilot distortion attack, a simple but devastating jamming strategy in which the adversary distorts the access point’s (AP) CSI measurement of even a single client leading to denial of service for all clients associated with the AP, and proposes multiple-antenna carrier frequency offset estimate (MACE) as a countermeasure that exploits the AP's antenna array to detect jamming with zero startup cost and zero additional network overhead.
