Interference suppression in the presence of quantization errors
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009Multi-element antennas offer the possibility of increasing the spatial reuse of wireless spectrum by “nulling” out interfering signals. However, the interference suppression performance is highly sensitive to small errors in the gains applied to the antenna elements.

Beampattern Synthesis With Blind Interference Suppression
IEEE Transactions on Signal Processing, 2012We suggest an adaptive blind interference suppression (BIS) beamformer that synthesizes a desired beampattern. For a strong interference, the principal eigenvector of the data sample covariance matrix approaches the array response at the interference direction.

Interference suppression of SRS
Quantum Electronics, 2011The theory of three-wave SRS is developed, which takes into account nonlinear dispersion of a medium for arbitrary phases of the pump waves at the input to the medium. The effect of interference suppression of SRS is predicted for values of the total phase of the three-wave pump (2n+1)π (n=0, ±1, ±2...), the effect being caused by the destructive ...

RF interference suppression for VDSL system
IEEE Transactions on Consumer Electronics, 2001This paper investigates the effect of radio frequency (RF) interference on the performance of very high-speed digital subscriber line (VDSL) system. It is shown that a blind equalization is extremely difficult in the presence of RF interference. A receiver structure, incorporating an adaptive notch filter (ANF) and hybrid DFE (H-DFE), is proposed to ...

Multipath Interference Suppression
2017Interferences on GNSS can be categorized into two types: intentional interference and unintentional interference. Jamming and spoofing, mainly discussed in Chaps. 2 and 4 in this book, belong to the category of intentional interference. Multipath interference studied in this chapter, and pulse interference that will be studied in Chap. 6 both belong to

A null despreader for interference suppression in GPS
International Journal of Satellite Communications and Networking, 2010AbstractThe Global Positioning System (GPS) utilizes low‐power spread‐spectrum signals and thus is vulnerable to various types of high‐power interference sources. It requires at least four satellites for estimating three‐dimensional user positions and the receiver clock bias.

Impact of Imperfections on Detectors for Interference Suppression
2010 IEEE Wireless Communication and Networking Conference, 2010In this paper, we carry out the performance analysis of recently proposed low complexity max log MAP detector for interference suppression under the realistic imperfections of correlation and non Gaussian alphabets. We also incorporate MMSE detector in our analysis taking into account non Gaussian alphabets however intricacy in the analysis of ...

A generalized RAKE receiver for interference suppression
IEEE Journal on Selected Areas in Communications, 2000Currently, a global third-generation cellular system based on code-division multiple-access (CDMA) is being developed with a wider bandwidth than existing second-generation systems. The wider bandwidth provides increased multipath resolution in a time-dispersive channel, leading to higher frequency-selectivity.

Interference suppression for uplink multiuser CDMA
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004Techniques are proposed for interference suppression for the uplink of multiuser CDMA systems. The multiuser CDMA uplink communication system model is described in space-time domain form through an antenna array and a multipath expression. A linear prediction technique is used to perform channel estimation.
