Binary time-frequency masks are powerful tools for the separation of sources from a single mixture. Perfect demixing via binary time-frequency masks is possible provided the time-frequencyâ€¦ (More)

We present a novel method for blind separation of any number of sources using only two mixtures. The method applies when sources are (W-)disjoint orthogonal, that is, when the supports of theâ€¦ (More)

Sparsity of representations of signals has been shown to be a key concept of fundamental importance in fields such as blind source separation, compression, sampling and signal analysis. The aim ofâ€¦ (More)

It is possible to blindly separate an arbitrary number of sources given just two anechoic mixtures provided the time-frequency representations of the sources do not overlap, a condition which we callâ€¦ (More)

This correspondence presents the results of the enumeration of Costas arrays of order 27: all arrays found, except for one, are accounted for by the Golomb and Welch construction methods.

The DUET blind source separation algorithm can demix an arbitrary number of speech signals usingM = 2 anechoic mixtures of the signals. DUET however is limited in that it relies upon source signalsâ€¦ (More)
