Keywords:
fast Fourier transform (FFT), filter with infinite impulse response (IIR-filters), system of linear algebraic equations (SLAE), digital signal processing
Abstract
The shortcomings of application of fast Fourier transformation algorithm at detection of separate tones of a signal are considered. The relevance of application of algebraic methods at demodulation of signals in modern information transmission systems is emphasized. The Goertzel algorithm of selective spectrum analysis is considered, the method of the linear algebraic processing of complex signal structures in case of detection of separate tones in a signal range is offered. The analysis of efficiency of the known and proposed method of selective spectrum analysis is carried out.Downloads
