OFDM is a promising technique being used for bandwidth efficient communication over the power-line channel. It provides excellent possibilities to adapt to the frequency-selectivity of the channel. The influence of impulsive noise on the OFDM transmission is not well analyzed yet. We choose Middletons Class A man-made noise model to statistically describe the impulsive interference and study th...

Costa’s celebrated ”writing on dirty paper” (WDP) shows that the powerconstrained channel Y = X + S + Z, with Gaussian Z, has the same capacity as the standard AWGN channel Y = X + Z, provided that the ”interference” S (no matter how strong it is) is known at the transmitter. While this ability for perfect interference cancellation is very appealing, it relies heavily on the Gaussianity of the ...

The transmitted symbol is affected by the channel noise and diversity is an efficient method to reduce the noise and interference. Recently, the channel noise is cancelled by using a novel beamforming technique, where the transmitted symbols are weighted and the same weighting vectors are used at the receiver. In this paper, the authors use the proposed beamforming technique in antenna diversit...

In the paper characteristic features of the corona noise from UHV transmission lines have been distinguished, which can be useful for the noise measurement under high level interference conditions. The utility of statistical methods in elimination of typical environmental interference has been shown, particularly methods based on the measurement of statistical spectra. The effect of inaccurate ...

A mainlobe interference suppression method is proposed in this paper, which can still work when the signal of interest (SOI) is present in the training data. In this method, the iterative adaptive approach (IAA) is applied to spatial spectrum estimation at first. Then, IAA spatial spectrum is used to reconstruct the interference-plus-noise covariance matrix (INCM). Next, the eigenvector associa...

Broadband wireless interference in a computer platform is the result of multiple dynamic electromagnetic emission sources. This interference is non-Gaussian and a receiver design based on the Gaussian assumption will yield suboptimal performance. In fact, it has a double-sided K-distribution and needs to be treated differently in the design process. When dealing with this type of interference i...

In this paper we investigate the performance of MIMO systems in co-channel interference. We present a way of explicitly examining the effect of interference on the MIMO sub-channel gains. Using this, we derive upper and lower asymptotic bounds on capacity with many interferers and in high interference-to-noise ratio. Simulation results are presented for these bounds and for the performance of M...

The performance analysis of ad hoc networks requires the characterization of the network’s self-interference. However, thus far, the exact distribution of the interference has been analytically tractable only for a path loss exponent of 4. Further, conventional power law decay models for signal propagation have a singularity at the origin that causes all the moments of the network self-interfer...

Intentional or unintentional interference and jamming is one of the major concerns in using the Global Positioning System (GPS) in various critical applications. In spite of the GPS frequency bands being protected by International and Federal Communication Commission (FCC) frequency assignments, there is always a chance of disruption of the GPS signal availability in critical times and applicat...

Difficulty with selective attention is a frequent complaint of adult patients with ADHD, but selective attention tasks have not provided robust evidence of attentional dysfunction in this group. Two experiments examine this puzzle by distinguishing between failures of spatial selection and problems due to sensitivity to perceptual interference. In Experiment 1, we measured the level of perceptu...
