A_Unified_CrossLayer_Framework

This code permit to simulate the sound received on microphones given their positions, the positions of the sound source(s), the frequency sampling of acquisition and the speed of sound. Assuming anechoical conditions.

The recognition of noise as a source of annoyance began in antiquity, but therelationship, sometimes subtle, that may exist between noise and money seems to be a development of more recent times. For example, the manager of a large wind tunnel once told one of the authors that in the evening he liked to hear, from the back porch of his home, the steady hum of his machine 2 km away, for to him the hum meant money. However, to his neighbours it meant only annoyance and he eventually had to do without his evening pleasure.

Orthogonal Least Squares Estimate on a plane, in the simple case of a linear equation, is in fact a problem that can be easily solved analytically with no approximation (see pdf file for detailed explanation). Notice that in the general multidimensional case, an analytical solution may not exist (although Mr. Carr s function is an efficient approximation of the solution).
