Listing of Communication in Scripts

This file computes the driving functions (delay and gain) for every single loudspeaker of a WFS - sytem, given by the array dimensions, the position of the virtual sound source and a reference line within the listening zone. The function arraysnap.m plots the resulting wavefield and shows the effect of spatial aliasing when you increase the frequency of the source signal or decrease the loudspeaker distance.

The aim of this toolbox is to compute blocking probabilities in WDM networks. This work was based on [1], [2], [3], [4] and user is referred to those papers for deeper study. Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources.

Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.

The two-step noise reduction (TSNR) technique removes the annoying reverberation effect while maintaining the benefits of the decision-directed approach. However, classic short-time noise reduction techniques, including TSNR, introduce harmonic distortion in the enhanced speech.

Wireless sensor networks offer an entire new field open for research and development. These types of networks conceptually offer many exciting features including scalability, self-configuration, self-healing, multicast routing, and easy deployment. For these reasons, they are well suited for a wide range of applications in monitoring, control, surveillance, and distributed sensing among many others.

Computes an orthogonal basis from a given criteria. Options are identical to those of sortwvfrms: basis are computed by signal width, localization, and noise. The vectors are sorted by the given criteria, projected onto a subspace orthogonal to the previously sorted vectors, and sorted in that subspace, then projected, etc.
