Noise cancellation in voice communication systems

A method for identifying a primary signal from a plurality of acoustic signals, the method comprising:

• receiving, by a processor (102), the plurality of acoustic signals associated with the plurality of sources, the plurality of acoustic signals comprising the primary acoustic signal and ambient noise;
• suppressing, by the processor (102), the ambient noise from the plurality of acoustic signals to obtain a first set of acoustic signals;
• separating, by the processor (102), each of the acoustic signal from the first set of acoustic signals;
• performing, by the processor (102), noise cancellation on each of the separated acoustic signal to obtain noise free acoustic signals;
• and
• mapping, by the processor (102), each noise free acoustic signal to respective source of sound to identify the primary signal.

A non-transitory computer-readable medium having a set of computer readable instructions that, when executed, cause a processor (102) to,

• filter a plurality of acoustic signals based on an amplitude;
• suppress ambient noise from the plurality of acoustic signals to obtain a first set of acoustic signals;
• perform a cross-correlation based localization to determine a number of acoustic signals and a number of sources associated with the first set of acoustic signals;
• cancel noise from each of the first set of acoustic signals to obtain a noise free set of acoustic signals;
• and
• map each noise free acoustic signal to respective source to identify a primary signal.
