Low-complexity successive intercell interference cancellation

2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012
Due to the data traffic explosion, cellular networks tend to have larger cell density and smaller cell size, which will give rise to significant intercell interference. In this work, we focus on receiver side signal processing techniques to perform intercell interference suppression and successive interference cancellation, where adaptive antenna ...

Advanced Successive Interference Cancellation for Non-Orthogonal Multiple Access

Telecommunications Forum, 2018
This paper proposes an advanced successive interference cancellation strategy for the non-orthogonal multiple access technique. The strategy is based on mapping the received signals into sub-groups.

Successive Interference Cancellation With Feedback for Random Access Networks

IEEE Communications Letters, 2017
We consider a random access network in which $K$ nodes wish to send independent packets to an access point (AP). In this letter, a novel method of feedback construction and an adaptive retransmission protocol of collided packets are proposed, which enable efficient successive interference cancellation at the AP.

Performance Enhancement of OAM-MIMO Using Successive Interference Cancellation

IEEE Vehicular Technology Conference, 2019
This paper proposes a method that employs successive interference cancellation (SIC) to further enhance the capacity of uniform circular array (UCA)-based orbital angular momentum (OAM)- MIMO systems.

Linear group-wise successive interference cancellation in CDMA

1988 IEEE 5th International Symposium on Spread Spectrum Techniques and Applications - Proceedings. Spread Technology to Africa (Cat. No.98TH8333), 2002
In this paper, we consider a matrix-algebraic approach to linear group-wise successive interference cancellation. As for both successive and parallel cancellation, it is shown that the general linear group-wise scheme corresponds to a one-shot linear matrix filtering. Furthermore, it is shown that if the general structure converges, it converges to the

Convergence of Linear Successive Interference Cancellation in CDMA

1998
In this paper we consider a matrix-algebraic approach to linear successive interference cancellation (SIC). It has been shown that both single- and multi-stage linear SIC schemes correspond to a one-shot linear matrix filtering. Eigenvalue conditions on the resulting linear filter for convergence of the multistage scheme are considered and the concept ...
