This paper proposes to make an assessment of speech signal protection in information leakage channel by frequency-time processing of complex measurement signal with a large base within a band equal intelligibility using Hilbert transform to represent it in an analytical form and preliminary reduction of the detection threshold n-multiples sequential synchronous accumulation of spectral components using direct and inverse fast Fourier transform. High accuracy and sensitivity assessment of the parameters of a complex measurement signal with a large base in information leakage channel on background high level of noise achieved by compensating with a minimum mean square error its time delay and frequency offset. |
