basic_ESPRIT.zip
This is a matlab program using ESPRIT method the estimate the frequency of a sinusoid wave. It is shown that this method finds out exactly the fact when there is no noise, but works worse than ML in accuracy in noise.

iterative_SNR_est.zip
This is a matlab program using the most liklihood method to estimate the SNR of a sinusoid wave. The experiment shows that it works well at normal SNR, while the noise is Gausian.

08-NTAV-SPA_165_Marciniak-Rochowniak-etal.zip
In this paper we propose a method for voice
activity detection (VAD) in a speech signal recorded in the
presence of noise. The so-called endpoint detection (EPD),
i.e., detection of voice activity (speech) boundaries is very
difficult if the signal is ...
