FIELD: technologies for digital data transfer, in particular, method for suppressing interference during multi-access transmission with temporal and/or frequency division of channels.
SUBSTANCE: relatively to previous level of engineering, structure of preliminary filtration is modified, where directly after complex-sign preliminary filtration projection onto complex vectors is performed. Thus it is supposed, that transmission with impulse-amplitude modulation is used with real-valued data series, and that channel impulse characteristics are sufficiently different from one another. Method can be used for case of distancing of antennas, and for mono-receipt. For preliminary filtration especially well fit are premonitory corrector filters with permitting check connection to real-valued check connection filter. Adjustment of these filters may be performed, for example, using minimal root-mean-square error algorithm.
EFFECT: efficient suppression of inter-modulation interferences.
