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

A new successive interference cancellation for asynchronous CDMA

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
This paper introduces a new multi-user detection method, successive interference cancellation based on the order of log-likelihood-ratio (LLR-SIC), for asynchronous code division multiple access (CDMA) systems. LLR-SIC operates on the fact that the most reliable user, i.e.

Successive interference cancellation in device-to-device communications

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Device-to-Device (D2D) communications is expected to gain importance in future cellular networks for spectrum efficiency. However, dealing with the interference in simultaneous D2D 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 ...

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.

Adaptive successive interference cancellation for the IS-95 uplink

Vehicular Technology Conference Fall 2000. IEEE VTS Fall VTC2000. 52nd Vehicular Technology Conference (Cat. No.00CH37152), 2002
In this paper we examine an adaptive successive interference canceler (ASIC) that can separate direct-sequence code-division-multiple-access (DS/CDMA) signals for the IS-95 (Interim Standard 95) uplink under near-far conditions, i.e., without power control.

A switching successive interference canceller for CDMA systems

Proceedings of the IEEE INDICON 2004. First India Annual Conference, 2004., 2005
Multiuser detection is an essential part of code division multiple access (CDMA) receivers to be able to exploit the bandwidth efficiency, i.e., to support as many users as possible. In this paper we propose a switching successive interference canceller (SSIC) for CDMA systems which dynamically switches between SIC and matched filter operations ...
