Echo Compensation by Equalizer with Precise Spectrum Estimation

The new adaptive equalizer is developed for echo compensation and for the optimal signal reinforcement. Test experiment is very simple and it does not require any hardware except a pair of microphones. The corresponding software and the identification of the model parameters are the main problems of the approach. They were solved with a new precise technique of phase estimation and with the standard Fourier analysis.
