Signal-interference bandpass filters with dynamic in-band interference suppression
2016 IEEE Radio and Wireless Symposium (RWS), 2016This paper focuses on the design of wide-band bandpass filters (BPFs) with dynamic in-band interference suppression. They are based on a new class of a signal-interference transversal filtering section (TFS) that consists of three signal paths that are effectively combined so that an absorptive notch (AN) — exhibiting theoretically infinite attenuation

Performance of OFDM with Blind Interference Suppression Schemes
2012 5th International Conference on New Technologies, Mobility and Security (NTMS), 2012In statistical wireless signal processing, extraction of unobserved signals from observed mixtures can be achieved through Blind Source Separation (BSS) algorithms. Orthogonal Frequency Division Multiplexing (OFDM) can be pronounced as one of the predominant multicarrier air interface communication technique.

An interference suppression mechanism for WSN
PROCEEDINGS OF 2013 International Conference on Sensor Network Security Technology and Privacy Communication System, 2013Wireless Sensor Network (WSN) is a centreless distributed wireless network constituted by mobile nodes without the help of any fixed infrastructure. Cooperation between nodes makes communication in WSN be achieved in complex environment with the deficiency of limited transmission distance made up by multi-hop forwarding so as to broaden the network ...

Enhancement of speech by suppression of interference
Proceedings of Third International Conference on Signal Processing (ICSP'96), 2002An algorithm has been developed which successfully separates a wanted voice from interfering voices and other sound sources. The system uses directional and harmonicity cues and is exceptionally robust to room reverberation. It does not rely on any prior information about the wanted or unwanted signals and is computationally efficient such that it is ...

Fat suppression by echo interference
Magma: Magnetic Resonance Materials in Physics, Biology, and Medicine, 1994Two spectral components of a binary system, like water and fat in proton magnetic resonance imaging (MRI) can be separated by adding two signals acquired with a different delay (the Dixon method). The same effect can be obtained in a single acquisition by interference of two shifted echoes.

Pulse Interference Suppression Techniques
2017Intentional interferences mainly include multipath interference and pulse interference. We studied multipath interference in the last chapter. In this chapter we study the suppression of the other type of intentional interference—the pulse interference.

Adaptive nonlinear suppression of interference
MILCOM 88, 21st Century Military Communications - What's Possible?'. Conference record. Military Communications Conference, 2003A signal processing technique designed to suppress interference in direct sequence spread spectrum receiving systems is described. The basic idea is to optimize the detection process dynamically in the presence of current interference. This is accomplished by estimating the statistics of the interference and then using this information to derive a ...

The measurement and suppression of radio interference
Journal of the British Institution of Radio Engineers, 1949The paper firstly outlines the nature of Radio Interference and the principles of measurement, goes on to describe measurement techniques as used by a manufacturer, and briefly reviews available methods of suppression and the difficulties encountered in their application.
