Lattice Reduction-Aided Successive Interference Cancelation for MIMO Interference Channels
IEEE Transactions on Vehicular Technology, 2014In 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, 2006In 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), 2002In 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, 2002We 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, 2007We 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, 2008This 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, 2011An 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 ...

Analysis of Successive Interference Cancellation in CDMA Systems
2012 Second International Conference on Advanced Computing & Communication Technologies, 2011In 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).

Analysis of Successive Interference Cancellation in D2D links
2016 Online International Conference on Green Engineering and Technologies (IC-GET), 2016The current trend in cellular communications is to clasp the device-to-device (D2D) paradigm in M2M scenario, as a mean to off-load, from the cellular infrastructure, the transmissions between devices in close proximity. This paper focuses mainly on the utilization of Successive Interference Cancellation technique in D2D links to support the M2M ...

Performance of cooperative CDMA with successive interference cancellation
2008 5th International Conference on Broadband Communications, Networks and Systems, 2008We investigate the BER and achievable rate of user cooperation schemes in practical uplink CDMA channels with multiple access interference (MAI). It is shown that when the system loading increases, cooperation alone becomes less effective if simple matched filters (MF) followed by combining from each partnerspsila signals are employed for obtaining ...
