Distributed Interference Cancellation

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
Distributed interference cancellation is considered for a single source and multiple collaborative receivers in the presence of multiple unknown interferers. Receivers observe interference in a distributed setting and collaborate to mitigate the common interference from multiple unknown interferers.

Cancellation accuracy in CDMA pilot interference cancellation

The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004
Pilot interference cancellation (IC) in mobile receivers has recently gained attention for CDMA cellular networks. In this paper we address the accuracy of the pilot interference cancellation at the receiver. In doing so, we consider the effects of channel estimation, timing estimation, receiver tap-spacing granularity, and the other receiver ...

RLS-based Interference Cancellation

2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2020
Adaptive Sinusoidal interference cancellation (ASIC) based on recursive least square (RLS) algorithm is proposed. RLS algorithm allows us to use a recursion instead of inversion of the autocorrelation matrix to evaluate the optimum weights. The main advantage of RLS algorithm is that it exhibits extremely high rate of convergence.

An efficient interference canceler

2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002
This paper deals with adaptive interference cancellation in the presence of array imperfections and beam pointing error. A new interference canceler with robust capabilities is proposed. This interference canceler first obtains the modified interference subspace (MIS) by employing the covariance differencing technique, then it obtains the projection ...

An eigenanalysis interference canceler

IEEE Transactions on Signal Processing, 1991
Eigenanalysis methods are applied to interference cancellation problems. While with common array processing methods the cancellation is effected by global optimization procedures that include the interferences and the background noise, the proposed technique focuses on the interferences only, resulting in superior cancellation performance. Furthermore,

Interference Cancelation Reception

2017
The integrated and/or hybrid satellite and terrestrial network has become more and more important because of its broad application prospect and has received considerable attention. At the same time, the integrated network also brings many challenges, especially the problem of interference.

Indirect Cochannel Interference Cancelling

Wireless Personal Communications, 2001
This paper describes a blind cochannel interference cancelling technique, indirect cochannel interference cancelling (ICIC), that cancels a constant envelope modulated interferer in cellular mobile radio communication channels. ICIC exploits the constant envelope property of the interfering signal to simplify the receiver structure.

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

Main-lobe interference canceler

IEEE Antennas and Propagation Society International Symposium 1992 Digest, 1992
A main-lobe interference canceller based on the signal cancellation effect of employing a pseudo-signal injection method is proposed. Both theoretical analysis and simulation results show that the proposed scheme effectively reduces the degradation in an adaptive array caused by main beam jamming. >

Interference cancellation in groups

Proceedings of 1995 IEEE International Symposium on Information Theory, 2002
Consider a multiuser white noise channel of bandwidth W Hz, white noise spectral density /spl eta//2, with M users all received at power P, all requiring the same rate R bits/sec. It is known that that there is a Shannon capacity for the channel and that it is achievable by FDMA.
