Successive Interference Cancellation-Based MIMO Detection

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.

Lattice Reduction-Aided Successive Interference Cancelation for MIMO Interference Channels

IEEE Transactions on Vehicular Technology, 2014
In multiple-input-multiple-ouput (MIMO) interference channels (IFCs), interference alignment (IA) with zero-forcing (ZF) linear detection can be used to achieve the maximum degrees of freedom (DoFs). However, ZF linear detection usually degrades the performance due to the noise enhancement in practical systems.

Efficient ISI cancellation for STBC OFDM systems using successive interference cancellation

IEEE Communications Letters, 2006
In this letter, we propose an efficient detection scheme for space-time block coded (STBC) orthogonal frequency-division multiplexing (OFDM) with insufficient cyclic prefix (CP). The proposed scheme employs successive interference cancellation (SIC) and cyclic prefix reconstruction (CPR) concepts.

Co-channel interference cancellation with successive cancellation in narrowband TDMA systems

2000 IEEE Wireless Communications and Networking Conference. Conference Record (Cat. No.00TH8540), 2002
In this paper, successive cancellation of co-channel signals is described in the context of TDMA mobile radio systems employing coherent receivers. Both symbol aligned and misaligned co-channel signals are studied. Signal separability, which is a major problem in successive cancellation of co-channel signals, is obtained using the relative timing delay

Blind successive interference cancellation for DS-CDMA systems

IEEE Transactions on Communications, 2002
We propose a blind successive interference cancellation receiver for asynchronous direct-sequence code-division multiple-access (DS-CDMA) systems using a maximum mean energy (MME) optimization criterion. The covariance matrix of the received vector is used in conjunction with the MME criterion to realize a blind successive interference canceler that is

Successive narrowband interference cancellation for OFDM systems

IEEE Communications Letters, 2007
We consider the problem of mitigating narrowband interference (NBI) in conventional orthogonal frequency-division multiplexing (OFDM) systems, wherein the presence of the NBI dramatically degrades the performances of both the linear zero-forcing and minimum mean-square error equalizers. A new receiver based on successive NBI cancellation is synthesized,

Groupwise successive interference cancellation for MIMO communication systems

2008 Canadian Conference on Electrical and Computer Engineering, 2008
This paper proposes a modified detection scheme which reduces the performance gap between the V-BLAST MMSE detection algorithm and the maximum likelihood (ML) detection. In V-BLAST detection algorithm error propagation due to unreliable decision feedback severely limits the system performance.

Successive interference cancellation for two-group resource allocation

2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011
An energy allocation scheme is developed for multi-code code division multiple access (CDMA) systems to allocate the total energy to two-groups of code channels whilst considering successive interference cancellation to minimize the allocated energy. With a simplified energy calculation formulation, the required computational complexity to improve the ...
