Partial Interference Suppression in Massive MIMO Systems: Taxonomy and Experimental Analysis
IEEE Access, 2021 Densely deploying Massive MIMO access points results eventually in cell-free systems. To achieve scalability, users should be allocated only to neighbouring access points as it is not realistic to assume that all access points serve all users.

Robust mainlobe interference suppression for coherent interference environment [PDF]
EURASIP Journal on Advances in Signal Processing, 2016 A mainlobe interference suppression method is proposed in this paper, which can still work when the signal of interest (SOI) is present in the training data. In this method, the iterative adaptive approach (IAA) is applied to spatial spectrum estimation at first.

Multiple Interacting Narrowband Interferences Suppression Algorithm for OFDM Systems
IEEE Access, 2020 The OFDM technology is widely used in wireless communication systems, but it is highly sensitive to narrowband interference (NBI). The existing NBI suppression algorithms are mainly for single NBI or multiple NBIs with an assumption that the frequency ...

Interclass Interference Suppression in Multi-Class Problems
Applied Sciences, 2021 Multi-classifiers are widely applied in many practical problems. But the features that can significantly discriminate a certain class from others are often deleted in the feature selection process of multi-classifiers, which seriously decreases the ...

Densely Deployed Indoor Massive MIMO Experiment: From Small Cells to Spectrum Sharing to Cooperation
Sensors, 2021 Massive MIMO is a key 5G technology that achieves high spectral efficiency and capacity by significantly increasing the number of antennas per cell. Furthermore, due to precoding, massive MIMO allows co-channel interference cancellation across cells.

Suppress interference by symbol-misalignment [PDF]
Proceedings of the 5th International ICST Conference on Communications and Networking in China, 2010 This paper studies the interference reduction, which is one the most important issue to increase the network throughput, improve the energy efficiency (green communication) and so on. In doing so, we first induce the system model consisting of one interfering node, based on several network examples. After that, the impact of time asynchrony between the

Multiple Mainlobe Interferences Suppression Based on Eigen-Subspace and Eigen-Oblique Projection
Sensors, 2022 When the desired signal and multiple mainlobe interferences coexist in the received data, the performance of the current mainlobe interference suppression algorithms is severely challenged. This paper proposes a multiple mainlobe interference suppression
