Toward Massive MIMO 2.0: Understanding Spatial Correlation, Interference Suppression, and Pilot Contamination

IEEE Transactions on Communications, 2019
Since the seminal paper by Marzetta from 2010, Massive MIMO has changed from being a theoretical concept with an infinite number of antennas to a practical technology.

Interference Suppression Using Location Aware Beamforming in 5G Ultra-Dense Networks

2020 IEEE Microwave Theory and Techniques in Wireless Communications (MTTW), 2020
Importance of three-dimensional beamforming in 5G wireless networks is due to increasing density of stations. Alignment of transmitter and receiver beams can lead to substantial interference suppression.

Multipath Interference Suppression

2017
Interferences on GNSS can be categorized into two types: intentional interference and unintentional interference. Jamming and spoofing, mainly discussed in Chaps. 2 and 4 in this book, belong to the category of intentional interference. Multipath interference studied in this chapter, and pulse interference that will be studied in Chap. 6 both belong to

Enhanced interference whitening for co-channel interference suppression

2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013
The co-channel interference (CCI) has become a major throughput-limiting factor for cell-edge users in the modern cellular systems such as the Long Term Evolution (LTE) network. Spatial interference whitening (IW) is an effective low-complexity linear method to suppress colored spatial interference in a MIMO setup.

Experimental Evaluation of Adaptive Beamforming for Automotive Radar Interference Suppression

IEEE Radio and Wireless Symposium, 2020
Mutual interference between automotive radars can make it difficult to detect targets, especially the weaker ones, such as cyclists and pedestrians. In this paper, the interference suppression performance of a Least Mean Squares (LMS) algorithm-based ...

Residual interference suppression in parallel interference cancellation receivers

1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003
Parallel interference cancellation (PIC) receivers are among the most promising receiver techniques for future code-division multiple-access (CDMA) systems. Interference cancellation efficiency relies on the knowledge of the number of users and propagation paths needed in multiple-access interference (MAI) estimation.

Pulse Interference Suppression Techniques

2017
Intentional interferences mainly include multipath interference and pulse interference. We studied multipath interference in the last chapter. In this chapter we study the suppression of the other type of intentional interference—the pulse interference.

Interference suppression of SRS

Quantum Electronics, 2011
The theory of three-wave SRS is developed, which takes into account nonlinear dispersion of a medium for arbitrary phases of the pump waves at the input to the medium. The effect of interference suppression of SRS is predicted for values of the total phase of the three-wave pump (2n+1)π (n=0, ±1, ±2...), the effect being caused by the destructive ...

Suppressing QPSK DS/CDMA interference

Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002
Three adaptive QPSK direct-sequence code-division multiple-access (DS/CDMA) receivers for suppressing QPSK DS/CDMA interference are introduced. Performance results for the three proposed receivers, as well as results for the linear correlation receiver, are provided.
