Research of the Hybrid Filter Bank Frequency Equalizer Transfer Function Coefficients Estimation Quality

This paper presents a method for calculating the quality of the estimation of the filter coefficients of the corrector of a hybrid filter bank, based on the error of the indirect estimation of the amplitude and phase of the equalizer coefficients. To confirm the correctness of the theoretical expressions, a hybrid filter bank was simulated with the addition of white Gaussian noise in the calibration path at different SNR values.
