dc.description.abstract |
In this paper a symmetric feedback
implementation scheme of a two microphones speech
enhancement is presented. This approach can be
extended for a subclass of signal separations where the
direct link is stronger than the interference link in the
both channels. We consider the coupling systems
modeled as a linear time-invariant Finite Impulse
Response (FIR) filters and propose new instrumental
variable-based adaptive filters solution to enhance the
noisy speech. The optimum filter weight adaptation is
based on two instrumental variable algorithms: the
generalized least mean square (GLMS) algorithms and
the overdetermined recursive instrumental variable
(ORIV) algorithms. A comparative study with other
adaptive algorithms is presented. |
