Performance analysis of the hybrid interference canceller for multiple access interference cancellation

Proceedings of IEEE. IEEE Region 10 Conference. TENCON 99. 'Multimedia Technology for Asia-Pacific Information Infrastructure' (Cat. No.99CH37030), 2003
In this paper we introduced a hybrid interference cancellation scheme combining parallel interference cancellation (PIC) and successive interference cancellation (SIC). The proposed hybrid interference cancellation has been compared with existing PIC, SIC and other hybrid cancellation schemes. The performance criteria used for comparison are complexity,

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 ...

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.

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 ...

Residual interference suppression in parallel interference cancellation receivers

1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003
Parallel interference cancellation (PIC) receivers are among the most promising receiver techniques for future code-division multiple-access (CDMA) systems. Interference cancellation efficiency relies on the knowledge of the number of users and propagation paths needed in multiple-access interference (MAI) estimation.

On the performance of linear parallel interference cancellation

IEEE Transactions on Information Theory, 2001
Summary: This paper analyzes the performance of the linear parallel interference cancellation (LPIC) multiuser detector in a synchronous multiuser communication scenario with binary signaling, nonorthogonal multiple access interference, and an additive white Gaussian noise channel.

Interference Cancellation and Detection Using Precoders

2009 IEEE International Conference on Communications, 2009
We consider interference cancellation for a system with two users when users know each other channels. The goal is to utilize channel information to cancel the interference without sacrificing the diversity or the complexity of the system. Before, in the literature, it was shown how a receiver with 2 receive antennas can completely cancel the ...

Interference cancellation for a multicellular CDMA environment

Wireless Personal Communications, 1996
This paper considers the performance of adaptive interference cancellation applied to a CDMA microcellular environment, by employing a circular cell geometry and a closed form expression for the Bit Error Rate of a CDMA system with interference cancellation to analyze the effect of out-of-cell interference. Results are presented which indicate that out-

Structured interference cancellation at a WCDMA terminal

Seventh International Symposium on Signal Processing and Its Applications, 2003. Proceedings., 2003
In third generation CDMA-based cellular mobile systems, loading fraction is going to be less than one due to interference limitations. In other words, to achieve an acceptable BER, the number of served users and hence used codes will be less than the spreading factor. Accordingly, the existence of unused codes implies the existence of a noise subspace,
