White Gaussian noise
ranging from zero to 200 % of the power of the
Weinstein, Optimization or two-dimensional signal constellations in the presence of Gaussian noise
For zero mean additive white Gaussian noise
([mu]=0), we have to calculate only [sigma].
In the literature survey, there are two types of noise commonly identified namely they are Gaussian noise
and impulse noise.
To investigate the robustness of the algorithm, the watermarked image is attacked by Average and Median Filtering, Gaussian noise
addition, JPEG and JPEG 2000 compression, Rotation, Resizing, Cropping and Histogram Equalization attacks.
Most of the speckle filters assume speckle which is modeled as a multiplicative noise and perform logarithmic operation transforms speckle into additive white Gaussian noise
Simulation result shows the bit error rate (BER) of MIMOOFDM system having 32 sub-carriers, with two transmits and two receive antennas over a Rayleigh fading with additive white Gaussian noise
DS-UWB technology has a signal similar to a Gaussian noise
source, which provides regulators with a clear choice on how to protect existing licensed and unlicensed (licensed exempt) spectrum users.
Distribution of the Phase Angle Between Two Vectors Perturbed by Gaussian Noise
The project, comprised of four phases, will include: UWB signal generation, including white Gaussian noise
, gated white Gaussian noise
, dithered narrow pulses, DS-UWB, and MB-OFDM; development of measurement methods to characterize UWB emissions and assess receiver susceptibility; and actual measurement of UWB emissions characteristics and interference susceptibility of both digital and analog C-band downlink receivers.
AMEX: WTT), a worldwide provider of test equipment, today introduced the NoiseCom J7000 Jitter Test System, a powerful new test instrument that alters serial signal streams by injecting Gaussian noise
in a way that reflects real world signal behavior.
Additionally, Xilinx also announced the availability of an Additive White Gaussian Noise
(AWGN) core designed to assist engineers in accurately measuring the bit error rate (BER) performance of communication systems.
