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 ...

Interference Suppression in Synthesized SAR Images [PDF]
IEEE Geoscience and Remote Sensing Letters, 2005 Radio interferences are becoming more and more an important source for image degradation in synthetic aperture radar (SAR) imaging. Especially at longer wavelengths, interferences are often very strong, and their suppression is required during data processing.

Interference suppression for DS/CDMA
IEEE Transactions on Communications, 1999A direct-sequence spread spectrum (DS/SS) receiver for suppressing multiple-access interference in direct-sequence code-division multiple-access (DS/CDMA) communication systems is introduced. The proposed receiver does not require knowledge of other users' spreading codes, timing, or phase information.

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.

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 ...

Sensing and suppression of impulsive interference
2009 Canadian Conference on Electrical and Computer Engineering, 2009Cognitive radios are slated to be the next generation of smart transceivers that can dynamically sense and respond to its immediate radio frequency (RF) environment. It is highly likely that the RF environment will vary with time as various interferers come and go out of the range of the target receiver.

FRFT-Based Interference Suppression for OFDM Systems in IoT Environment
IEEE Communications Letters, 2019The OFDM technology has been widely used in 4G, 5G, and other wireless communication systems for its anti-frequency selective fading and high spectral efficiency. However, OFDM systems are very sensitive to narrowband interference (NBI).

The Main Lobe Interference Suppression Algorithm for Wideband Interference [PDF]
2018 14th IEEE International Conference on Signal Processing (ICSP), 2018 The main lobe interference suppression technique for wideband noise interference is studied in this paper, which is based on the space-time adaptive processing (STAP). One is the singular value decomposition (SVD-STAP) algorithm, it can have better beam-conserving ability when the expected signal power is low or even zero power, but it is needed in ...

Ionospheric Interference Suppression in HFSWR
2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006Over the past two decades, significant advances have been made in the use of high frequency surface wave radar (HFSWR) for remote sensing in an ocean environment. As one of the main outside interference, ionospheric interference may badly affect radar's performance.
