This paper presents a delayed instantaneous demixer (DID)
for speech signal separation from real recordings. Based
on the fact that the original signals are colored and mutually
uncorrelated, a simple algorithm is derived to estimate
the parameters of the demixer. This algorithm consists of
two parts: a grid searching method to estimate time delays
and an alternating projection method to estimate gain coefficients.
Experimental result demonstrates the performance
of the model and the algorithm.
