In this paper we study distribution of zeros and growth of solutions of second order linear equations depending on the coefficients of the equation and their (α, β)-order. We obtain results in general form, which considerably extend some results from [21].

This paper proposes an efficient reconfigurable hardware design of dual microphone speech enhancement technique using sound source localization and multi band spectral subtraction methods with elimination of background noise. Firstly, we have used a time delay of arrival algorithm using phase transform (PHAT) to achieve the time difference between the microphone signals. PHAT based filter can reach...

This paper, presents a design and implementation of dual microphone coherence based speech enhancement technique using field programmable gate array (FPGA). In order to have a proper enhancement of dual microphone system, we require to estimate the time delay of arrival (TDOA) between the two microphone signals which is followed by the application of the proposed speech enhancement algorithm. We have...

In this paper we study the comparative growth properties of a composition of entire and meromorphic functions on the basis of the relative order (relative lower order) of Wronskians generated by entire and meromorphic functions.

This paper proposes an efficient hardware architecture for the spectral subtraction algorithm applied to speech enhancement. Spectral subtraction algorithm is widely used in audio de-noising applications. The proposed architecture uses a novel approach to estimate environmental noise from speech adaptively. After estimating the noise from the input speech the noise samples are subtracted, making it...
chapter
As technology advances, more complicated systems requiring sophisticated algorithms often involving very complex digital signal processing (DSP) techniques are required. Therefore, hardware implementation of DSP algorithms has gained much attention during past years. One of the major applications of DSP is speech enhancement by eliminating the background noise. Spectral subtraction techniques in audio...
