Computationally simplified realization of the compensator of dispersion distortions on the basis of the filter bank

The article proposes a computationally effective scheme of the dispersion distortions compensation device, based on the modification of the classical 2M-channel digital filter banks. The modification consists in adding additional compensation delays, phase shifts and interpolation filters in the synthesis channels, determined by the calculation method, depending on the frequency dispersion slope of the ionospheric channel. Reduction of the number of arithmetic operations of is achieved by applying a polyphase structure of synthesis and analysis filters and applying the fast Fourier transform. Interpolator filters are needed to solve the problem of compensating for group delays in subchannels equal to the fractional values of the sampling intervals.
