SINR Statistics of Correlated MIMO Linear Receivers [PDF]
IEEE Transactions on Information Theory, 2013 Linear receivers offer a low complexity option for multi-antenna communication systems. Therefore, understanding the outage behavior of the corresponding SINR is important in a fading mobile environment. In this paper we introduce a large deviations method, valid nominally for a large number M of antennas, which provides the probability density of the ...

Active Attack on User Load Achieving Pilot Design in Massive MIMO Networks [PDF]
, 2017 In this paper, we propose an active attacking strategy on a massive multiple-input multiple-output (MIMO) network, where the pilot sequences are obtained using the user load-achieving pilot sequence design. The user load-achieving design ensures that the

Quadratically Constrained Beamforming Robust Against Direction-of-Arrival Mismatch [PDF]
, 2007 It is well known that the performance of the minimum variance distortionless response (MVDR) beamformer is very sensitive to steering vector mismatch. Such mismatches can occur as a result of direction-of-arrival (DOA) errors, local scattering, near-far ...

Min-SINR Maximization for mmWave Massive MISO-NOMA System With Randomly Directional Beamforming
IEEE Access, 2020 Based on the high-direction characteristic of millimeter wave (mmWave) transmission, randomly directional beamforming (RDB) can be used for the mmWave massive multiple-input single-output (MISO) non-orthogonal multiple access (NOMA) system to reduce the ...

User relay assisted traffic shifting in LTE-advanced systems [PDF]
, 2013 In order to deal with uneven load distribution, mobility load balancing adjusts the handover region to shift edge users from a hot-spot cell to the less-loaded neighbouring cells.

Anaerobe, 2019 Clostridioides difficile is a Gram-positive, anaerobic bacterium. It is known that C. difficile is one of the major causes of antibiotic associated diarrhea. The enhanced antibiotic resistance observed in C. difficile is the result of highly resistant spores produced by the bacterium.
