DEVICE FOR BROAD-BAND INTERFERENCES SUPPRESSING Russian patent published in 2016 - IPC H04B1/10 

FIELD: wireless communications.

SUBSTANCE: invention relates to radio communication equipment and can be used in radio communication systems, operating under conditions of broadband interferences sources action, different from signal by spatial characteristics. Under real operating conditions antenna-feeder systems (AFS) DD are frequently subjected to non-controlled changes, which can lead to errors in determining values of weight coefficients, using which correcting signals generation is performed. In order to overcome said disadvantage required values of weight coefficients are calculated in interferences adaptive compensation (IAC) unit. Then broadband interferences suppression device, is device, which includes series-connected AFS, radio receiving devices linear channels, in which input of main radio receiving device is connected to AFS output corresponding to main AFS DD, and other inputs are connected to corresponding AFS outputs, having numbers from one to N. IAC comprises set of Ν∗(Ν+1)/2 of single-type weight coefficient generators (WCG). In each of WCG after selecting of all weight coefficient values, variable in given range of values with specified pitch, at WCG output weight coefficient value is generated, providing maximum signal-to-noise ratio for this implementation. All computational operations are controlled and synchronized using computer by corresponding control, data and address buses.

EFFECT: technical result is increased adaptation suitability to real conditions of operation.
