DEVICE FOR GENERATING QUADRATURE AMPLITUDE-MODULATED SIGNALS Russian patent published in 2015 - IPC H04L27/20 

FIELD: radio engineering, communication.

SUBSTANCE: device for generating quadrature amplitude-modulated signals comprises a common driving generator, three phase changers, four switches, an adder, first and second variable-ratio voltage dividers having two inputs and one output, to the first input of which a signal is transmitted from the output of a device for controlling the value of low-level signals E_k and D_k, comprising an analogue-to-digital converter, read-only memory and a digital-to-analogue converter.

EFFECT: reduced loss of throughput of a discrete channel in a bad interference environment.
