Interference suppression of SRS

Quantum Electronics, 2011
The 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, 2009
Cognitive 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.

Interference suppression by biased nonlinearities

IEEE Transactions on Information Theory, 1995
A method for suppressing the interference by biased nonlinearities is presented. The memoryless nonlinearity taken into account is of the form \(y(x) = (|x |- \xi)^\nu\) for \(|x |> \xi\), and \(y(x) = 0\) for \(|x |\leq \xi\), where \(\xi > 0\) and \(\nu\) a positive number greater than \(-1\).

Adaptive nonlinear suppression of interference

MILCOM 88, 21st Century Military Communications - What's Possible?'. Conference record. Military Communications Conference, 2003
A 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 ...

Median filters to suppress interference

2015 IEEE International Symposium on Electromagnetic Compatibility (EMC), 2015
Median filters can be successfully used to eliminate impulsive interference and noise on signal lines overcoming the difficulties of linear filters, which are not suitable to address this problem. Median and median type filters have been popular for the last forty years; they found their main applications in image and speech processing.

Ionospheric Interference Suppression in HFSWR

2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006
Over 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.

Code-aided interference suppression for DS/CDMA communications. I. Interference suppression capability

IEEE Transactions on Communications, 1997
A code-aided technique for the simultaneous suppression of narrow-band interference (NBI) and multiple-access interference (MAI) in direct-sequence code-division multiple-access (DS/CDMA) networks is proposed. This technique is based on the linear minimum mean-square error (MMSE) algorithm for multiuser detection.

Enhanced interference whitening for co-channel interference suppression

2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013
The co-channel interference (CCI) has become a major throughput-limiting factor for cell-edge users in the modern cellular systems such as the Long Term Evolution (LTE) network. Spatial interference whitening (IW) is an effective low-complexity linear method to suppress colored spatial interference in a MIMO setup.

The Main Lobe Interference Suppression Algorithm for Wideband Interference

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 ...
