Successive Interference Cancellation for Underwater Acoustic Communications

IEEE Journal of Oceanic Engineering, 2011
In this paper, we introduce the addition of an iterative, successive interference cancellation (SIC) process to improve on a multiuser, single-input-multiple-output (SIMO) communications receiver using passive time reversal as a space-time preprocessor.

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

Successive interference cancellation techniques for LTE downlink

2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011
Successive interference cancellation (SIC) is a well-known technique for mitigating interference. For multiple-layer reception, hard-decision SIC with perfect per-layer rate control has been proven to be a capacity-achieving scheme. In practice, however, due to imperfect rate control and signaling constraints, there is a potential for certain variants ...

Successive Interference Cancellation in Device-to-Device Communications

2021
Device-to-Device (D2D) communications is expected to gain importance in future cellular networks for spectrum efficiency. However, dealing with the interference in simultaneous D21) and cellular transmissions is a significant challenge. In this paper, the problem of optimal pairing of D2D and CU transmissions is addressed in order to control ...

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.

Successive interference cancellation in multicarrier DS/CDMA

IEEE Transactions on Communications, 2000
In this paper, we present a successive interference cancellation (SIC) scheme for a multicarrier (MC) direct-sequence code-division multiple-access (CDMA) system, using band-limited spreading waveforms to prevent self-interference. In every subband, the SIC receiver successively detects the interferers' signals and substracts them from the user-of ...

Mitigating Error Propagation in Successive Interference Cancellation

IEICE Transactions on Communications, 2006
In this letter, we propose a novel signal detection method for spatially multiplexed multiple input multiple output (MIMO) systems, based on the idea of ordered successive interference cancellation (OSIC). In the proposed method, we try every possible value as the first detected symbol instead of making a decision. Although the proposed method requires

Successive interference cancellation for cooperative communication systems

Proceedings of the 2009 International Conference on Hybrid Information Technology, 2009
In this paper, we analyze and simulate a successive interference cancellation (SIC) scheme for cooperative communication systems in wireless communication network. In the interference cancellation strategy, co-channel interference (CCI) is mitigated by zero forcing (ZF) or minimum mean square error (MMSE) receivers.

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.
