Sentence examples for from pilot contamination from inspiring English sources

As we know, center users still suffer from pilot contamination; thus, their SINR are the same as (10).

Such systems suffer from pilot contamination during channel estimation, due to the shortage of orthogonal pilot sequences.

Differently, edge users do not suffer from pilot contamination because they are assigned with orthogonal pilot sequences.

By setting the threshold and neglecting these taps, a huge part of the noise and interference from pilot contamination will be eliminated.

We assume all transmissions in the system are synchronized, which represents a worst-case scenario from a pilot contamination perspective, as argued in [2].

The key in our solution is a channel estimation that incorporates multiple time slots so that it can benefit from randomization of the pilot contamination.

When reusing the same pilot from two transmitters, the negative consequences derived from interferences are referred to as pilot contamination.

This study originated from a need to reduce the pilot contamination in massive MIMO systems.

The approximate MSE in (14) for the proposed estimator decreases with increasing transmitting power q, increasing M or decreasing β iik, which means smaller interference level from other cells, i.e., smaller pilot contamination.

The second category divides the users into two groups according to different levels of pilot contamination, namely the center users who suffer from the modest pilot contamination and the edge users who suffer from severe pilot contamination.

The authors adopt MMSE channel estimation for the analysis of pilot contamination and the achievable rates in a massive MIMO system suffering from such problem.
