Deep Learning-aided Successive Interference Cancellation for MIMO-NOMA

Global Communications Conference, 2020
This paper introduces a novel deep learning (DL) based successive interference cancellation (SIC) scheme for an uplink multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) system.

Analysis of Successive Interference Cancellation in CDMA Systems

2012 Second International Conference on Advanced Computing & Communication Technologies, 2011
In DS/CDMA systems, overcoming near/far effects and fading is imperative for satisfactory performance. One way to combat the near/far effect is to use stringent power control, as is done in most of the commercial systems. Another approach is Multi-User Detection (MUD).

Opportunistic Power Control for Successive Interference Cancellation

IEEE Communications Letters, 2011
This letter proposes an opportunistic power control for increasing the transmission rate of a secondary transmitter (ST) in frequency reused scenario. The environments considered herein have multiple primary transmitter/receiver pairs and one secondary transmitter/receiver pair using the same frequency band.

Frequency-Domain Successive Cancellation of Nonlinear Self-Interference With Reduced Complexity for Full-Duplex Radios

IEEE Transactions on Communications, 2022
Nonlinear self-interference (SI) cancellation is crucial for eliminating the impact of the transmitter-side nonlinearity on the comprehensive SI cancellation performance in full-duplex radios.

Maximal Conditional Efficiency Successive Interference Cancellation [PDF]

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
Conditional asymptotic multi-user efficiency is introduced as a quantitative measure for comparing the performance of multi-user detectors that employ successive interference cancellation (SIC). For a given ordering of user signals, we derive the detector that achieves the maximum asymptotic conditional efficiency for each user among all possible SIC ...

DS/CDMA successive interference cancellation

Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94), 1995
Conventional DS/CDMA detectors operate by enhancing a desired user while suppressing other users, considered as interference (multiple access interference, MAI) or noise. A different viewpoint is to consider other users not as noise but to jointly detect all users' signals (multiuser detection). This has significant potential of increasing capacity and

On the effect of cancellation order in successive interference cancellation for CDMA systems

2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003
We study the effect of cancellation order on bit error rate (BER) performance of a code division multiple access (CDMA) system employing a linear successive interference cancellation (SIC) receiver in both an additive white Gaussian noise (AWGN) channel and a Rayleigh fading channel. Four different ordering schemes are studied.

Successive cancellation for cyclic interference channels

2008 IEEE Information Theory Workshop, 2008
The Chong-Motani-Garg inner bound for the two-user interference channel is generalized to a special case of many-user interference channels. By taking a geometric viewpoint and using rate-splitting arguments, it is shown that all operating points in the Chong-Motani-Garg inner bound allow decoding by successive cancellation at all receivers.

On the Design of Massive Non-Orthogonal Multiple Access With Imperfect Successive Interference Cancellation

IEEE Transactions on Communications, 2019
In this paper, we address a practical but adverse problem that successive interference cancellation (SIC) is imperfect in a massive non-orthogonal multiple access (NOMA) system.
