According to the basic ICA theory, independency is measured by non-Gaussianity, and minimizing H y n f is equivalent to maximizing the non-Gaussianity, which is responsible for separating data in individual frequency bins.
In FDBSS, observed signals are transformed to time-frequency (T-F) domain via short time Fourier transform (STFT) first, so that the convolutive mixture in the time domain becomes instantaneous mixture in individual frequency bins.
Unlike temporal noise shaping (TNS) [7], which also uses FDLP and forms a part of the MPEG-2/4 AAC codec, where FDLP is applied to solve problems with transient attacks (impulses), the proposed codec employs FDLP to approximate relatively long (hundreds of milliseconds) segments of Hilbert envelopes in individual frequency sub-bands.
To avoid spurious findings in individual frequency bins, we introduced the requirement that 2 neighboring frequency bins differ significantly between conditions.
While ICx cells are sensitive to the correlation across all inputs, we are examining the causes of variability in individual frequency channels across contexts.

However, these techniques are less successful in identifying isolated spikes or in separating individual frequency components.
To compare the amplitude of the mean network timecourses across groups in the individual frequency bands General Linear Model (GLM) based test was used.
Aβ plaques, neurofibrillary tangles, and Lewy bodies do not occur in high enough individual frequency to explain their co-existence in AD-LBV brains [ 17, 18].
The Rome III FD questionnaire consists of 18 items with answers in ordinal scale and individual frequency thresholds.
Rivet Joints have the ability to scan automatically across an array of communications frequencies, allowing an operator to home in on individual frequencies and pass that information on to the Awacs radar or J-Stars ground-surveillance planes, which have better ability to pinpoint the locations of the transmissions.
This paper deals with asymptotic rejection of individual frequency modes in nonlinear systems under general periodic disturbances.
