MODE OF RADIO COMMUNICATION Russian patent published in 2007 - IPC H04B7/12 

FIELD: the invention refers to the field of radio communication and may be used in duplex radio lines of communication with using complex signals.

SUBSTANCE: the achieved technical result is expansion of functional possibilities of the mode of radio communication by way of realization of the duplex principle of transmission and reception of discrete and analog information between two points on two frequencies. In the mode of radio communication at the first point a formed complex signal with combined phase manipulation and amplitude modulation is converted by frequency with using frequency ω_r1 of the first heterodyne, the voltage of the first intermediate frequency is singled out equal to the sum of frequencies ω_int1= ω_с + ω_r1, intensified on power and radiated on frequency ω₁=ω_int1=ω_r2 and then a complex signal is received on frequency ω₂=ω_r1, intensified, converted on frequency with using frequency ω_r2 of the second heterodyne, the voltage of the second intermediate frequency is singled out and limited, an additional information channel is singled out and transmitted. At that at the second point a complex signal is radiated on frequency ω₂ and received on frequency ω_1.

EFFECT: expands functional possibilities of the mode.
