Wideband Interference Cancellation in Adaptive Sidelobe Cancellers

IEEE Transactions on Aerospace and Electronic Systems, 1983
This paper presents numerical results from a study of sidelobe cancellers operating against wideband interfering signals. The study was designed to provide information that would be useful to system designers. Among other things, we address the question of whether it is best to enhance the bandwidth capability of the canceller by using tapped delay ...

Successive Interference Cancellation in Heterogeneous Networks

IEEE Transactions on Communications, 2014
At present, operators address the explosive growth of mobile data demand by densification of the cellular network so as to reduce the transmitter-receiver distance and to achieve higher spectral efficiency. Due to such network densification and the intense proliferation of wireless devices, modern wireless networks are interference-limited, which ...

Interference Cancellation of AM Narrowband Interference Signals

2007 IEEE 65th Vehicular Technology Conference - VTC2007-Spring, 2007
In this paper, we consider an overlay system where narrowband AM signals interfere with a broadband multicarrier system (M. Schnell et al., 2004). To reduce the effect of the AM narrowband interference on the multicarrier system, we propose a low complexity algorithm to estimate AM narrowband interference.

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,

Optical CDMA Serial Interference Cancellation: First Cancellation Stage

2007 International Multi-Conference on Computing in the Global Information Technology (ICCGI'07), 2007
Multiple access interference (MAI) is a primary concern in optical coded division multiple access (OCDMA). To alleviate this issue, first cancellation stage of an optical serial interference cancellation (O-SIC) can be employed. In this paper, we investigate the effect of optical serial interference cancellation for the first cancellation stage on bit ...

Adaptive Interference Cancellation: Cancellation Performance vs. Computational Overhead

2008 Proceedings of 17th International Conference on Computer Communications and Networks, 2008
Superposition interference cancellation (SIC) has been highlighted due to its high spatial reuse efficiency in wireless networks. It exploits superposition aspect of multiple signals to cancel interferences. We present three basic SIC schemes, which are (1) superposition demodulation scheme, (2) superposition decoding scheme and (3) iterative ...

Equalization and Interference Cancelation

2011
This chapter concentrates on the modeling of intersymbol interference (ISI) channels and the various signal processing methods for recovering digital information transmitted over such channels. The chapter begins with a treatment of ISI channel modeling, including a vector representation of digital signaling on ISI channels. We then develop the maximum

Interference Management versus Interference Cancellation: SATCOM Case

2011
Interference management and interference cancellation are addressed in the satellite communication (SATCOM) system. We first introduce the two options for a multibeam payload: flexible (FLEX) where allocation is fully flexible in the frequency domain, and conventional on which beamforming (BF) is applied. Further, two optimization problems are proposed,

Filter Design for Self-Interference Cancellation

2020
Mitigation of self-interference is the prime challenge in making full-duplex technology feasible in wireless communications. In this chapter, we first present system model of a wireless communication link including a source, full-duplex transceiver, and destination, and discuss different approaches and assumptions when building the signal model.

Beyond digital interference cancellation

2010
One of the major drawbacks towards the realization of MIMO and multi-sensor wireless communication systems is that multiple antennas at the receiver each have their own separate radio frequency (RF) front ends and analog to digital converter (ADC) units, leading to increased circuit size and power consumption.
