Another important problem with massive MIMO is pilot contamination.
By exploiting the merit of massive MIMO, simultaneous pilot and data transmission of other users has little impact on the first user's uplink data detection.
Further research is needed to investigate the role of morbilliviruses on the health and massive deaths of pilot whales and other cetaceans.
They really were originators, on the verge of making two epochal albums: in 1989, Nellee Hooper produced Soul II Soul's Club Classics Vol. One; two years later five others piloted Massive Attack's debut, Blue Lines, which, if anything, was even more influential.
"Airline industry facing a massive shortfall of pilots".
For a typical massive MIMO system, the pilot sequences used within a specific cell are orthogonal, but the same pilot group is typically reused in the adjacent cells due to the limited number of orthogonal pilot sequences.
In this work, we have introduced a simple and practical channel estimator for massive MIMO TDD systems with pilot contamination in a flat channel environment.
A semi-blind iterative space-alternating generalized expectation maximization (SAGE) based channel estimation algorithm for massive MIMO systems with pilot contamination is proposed in [13].
This again strengthens the motivation and effectiveness of our proposed pilot design.Generally, massive MIMO in many cases works at low SNRs.
If that's not enough, it seems that you can also use Star Wars blasters and pilot a massive Imperial Star Destroyer through the Los Santos sky. .
