FIELD: noise suppression depending on intelligent antenna.
SUBSTANCE: proposed method involves beam generation for digital output signal of receiver depending on intelligent antenna with aid of beam shaping matrix, generation of range of digital signals of Nrk(m), suppression of main beam signals of other users contained in Nrk(m), generation of other range of digital signals of NSk(m), incorporating only desired signal and all noise signals, search for NSk(m) in digital signal, and generation of all multibeam propagation signals arriving from other users, as well as suppression of noise signal due to multibeam propagation in Nsic(m), alignment of main beam signal and signal of each multibeam propagation including phase coincidence, and generation of digital signal incorporating suppressed noise, which should ensure noise suppression.
EFFECT: enhanced reliability of noise suppression.
