INTERFERENCE SUPPRESSION DEVICE FOR RECEIVERS OF WIDE- BAND SIGNALS Russian patent published in 1998 - IPC

FIELD: radio communication. SUBSTANCE: device has three subtracters, inputs of which are combined with device input. First subtracter output is connected to second input of second subtracter through series-connected first multiplier, band-pass filter, phase inverter and second multiplier. Second subtracter output is connected to input of first unit with controlled transmission ratio. First unit output is connected to second input of first subtracter and to second input of third subtracter 9 through series- connected limiter, synchronous phase filter, second input of which is connected to device input and through second unit with controllable transmission ratio. Third subtracter output serves as device output. Reference signal is supplied to multipliers from signal copy generator. EFFECT: enhanced interference suppression. 2 dwg
