Massive MIMO is, in general, severely affected by pilot contamination. As opposed to traditional detectors, we propose a group-blind detector that takes into account the presence of pilot contamination. While sticking to the traditional structure of the training phase, where orthogonal pilot sequences are reused, we use the excess antennas at each base station to partially remove interference during the uplink data transmission phase. We analytically derive the asymptotic SINR achievable with…

This work performs an uplink large system analysis of multi-cell multi-antenna system when the receiver employs a matched filtering with a pilot contaminated estimate and finds the asymptotic Signal to Interference plus Noise Ratio (SINR) as the number of antennas and number of users per base station grow large while maintaining a fixed ratio.

Inter-Cell Interference in Noncooperative TDD Large Scale Antenna Systems

This paper shows that the contamination of the channel estimates happens whenever a pilot sequence is received at a base station simultaneously with non-orthogonal signals coming from other users, and proposes a method to avoid such simultaneous transmissions from adjacent cells, thus significantly decreasing interference.

Large-sample performance of blind and Group-blind multiuser detectors: a perturbation perspective

A perturbation technique is developed rigorously and systematically to analyze blind and group-blind multiuser detection detectors using either the sample data covariance matrix directly or its eigencomponents and corresponding results can be applied to a practical system of a given sample size.

Large-system performance analysis of blind and group-blind multiuser receivers

The results reveal an interesting "saturation" phenomenon: the output SINR of each of these receivers converges to a finite limit as the signal-to-noise ratio of the desired user increases, which indicates that the capacity of a wireless system with blind or group-blind multiuser receivers is not only interference-limited, but also estimation-error limited.
