... POSTFILTERING USING MULTICHANNEL SPECTRAL ESTIMATION In this section, a postfiltering method employing two new multichannel spectral estimators is proposed to suppress fur- ther the undesired sources in ... the postfilter with spectral estimation using an inner product has a slightly higher in- terference suppression level than the postfilter with spectral estimation...

... Advances in Signal Processing of a binding process [7–9]. However, analyte estimation therein is typically performed using only the data collected in the equilibrium, and rarely relies on the kinetics ... [10]. In [11], analyte targets in real-time DNA microarrays are estimated using the temporally sampled kinetics of the binding process. However, the kinetics process there is d...

... rate savings by merging quantization bins. The bin-merging technique exploits the fact that certain combinations of quantization bins at each node cannot occur because the corresponding spatial ... in S Q corresponds to one region in sensor field which is obtained by computing the intersection of M ring-shaped areas (see Figure 2). For example, using an j th element Q j = (Q 1 , , Q M )i...
