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.

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.

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.

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

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 ...

Interference suppression by biased nonlinearities
IEEE Transactions on Information Theory, 1995It is shown that, when the input signal-to-interference ratio (SIR) is small, a biased nonlinearity that has a dead zone below some threshold value can provide a large enhancement in output SIR and signal-to-interference-plus-intermodulation ratio (SIIMR) if the threshold is set equal or close to the amplitude of the strong interference. In the absence

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.

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 ...

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 ...

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.
