Starting from the 3D recording space receiver-source-frequency, they estimate observables in the 3D estimation space DOA-DOD-TOA.
In the receiver, each source vector is reconstructed by a WZ decoder.
Simply attach your receiver's "source output" or "video output" into one of the inputs on your TV.
In order to obtain consistent results, we repeated each experiment (for a given distance and T 60) by varying the position of the receiver and the source, keeping the source-receiver distance and the reverberation time fixed.
Five parameters, including visibility, height, and width of the tree belt, height of receiver and noise source, and the distance between noise source and receiver, were studied.
If the angular opening of the wedge is smaller than and both the receiver and the source fall inside the wedge, then source and receiver are in direct visibility.
The five parameters were then transformed into three-dimensionless parameters, i.e., h′: receiver and noise source height/tree height, d′: distance between noise source and receiver/tree height, and m′: belt width/visibility.
Moreover, a nonlinear DFE receiver recovers the source signals successively by exploiting the finite alphabet property of the source signals.
Subsystems of source, receiver and isolators are represented by Fourier transforms of their mobility matrices.
