Successive interference cancellation techniques for LTE downlink
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011Successive 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 ...

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 ...

Successive interference cancellation in device-to-device communications
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017Device-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 ...

DS/CDMA successive interference cancellation
Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94), 1995Conventional 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

Maximal Conditional Efficiency Successive Interference Cancellation
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006Conditional 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 ...

A new successive interference cancellation for asynchronous CDMA
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004This 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.

Opportunistic Power Control for Successive Interference Cancellation
IEEE Communications Letters, 2011This 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, 2000In 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 ...

Low-complexity successive intercell interference cancellation
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012Due to the data traffic explosion, cellular networks tend to have larger cell density and smaller cell size, which will give rise to significant intercell interference. In this work, we focus on receiver side signal processing techniques to perform intercell interference suppression and successive interference cancellation, where adaptive antenna ...
