FIELD: radio engineering; measuring technology.
SUBSTANCE: radio engineering; digital information processing systems and measuring technology. Invention can be used for digital filtering (separation) of radio pulses with partially overlapping spectra contained in a group signal in the accepted implementation, in communication systems in cellular communication systems for multiplexing selected frequency bands. The technical result of the invention is the possibility of using radio pulses with partially overlapping spectra in radio engineering devices, carrying out additional channel multiplexing in communication systems with frequency division of channels and eliminating interfering radio pulses (noise) in their non-orthogonality area. The method for digital filtering of radio pulses with partially overlapping amplitude-frequency spectra additionally includes the formation of correlation matrix elements that determine the relationship between radio pulses of the group signal, the formation of elements of the inverse correlation matrix, the formation of pulse sequences, convolution of the input sequence with the generated pulse sequences. A device that implements a method for digital filtering of radio pulses with partially overlapping amplitude-frequency spectra additionally includes a block in which elements of the inverse correlation matrix are formed, a block in which M pulse sequences are formed, and a block that implements convolution of the input sequence with pulse sequences.
EFFECT: possibility of using radio pulses with partially overlapping spectra in radio engineering devices, carrying out additional channel multiplexing in communication systems with frequency division of channels and eliminating interfering radio pulses (noise) in their non-orthogonality area.
