RADIO RECEIVER Russian patent published in 2016 - IPC H04B7/08

Abstract RU 2583848 C2

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used to receive randomly distributed frequency-modulated signals in conditions of mobile objects and multi-beam signal propagation. Radio receiver includes two antenna inputs, each of which consists of series-connected filter preselector first amplifier, mixer, intermediate frequency filter, second intermediate frequency amplifier, an analogue-digital converter, a complex mixer and a local oscillator, which outputs are connected to second inputs of mixers each antenna input block with software analysis and output data generating unit. Outputs of mixers are connected to integrated analysis unit for signal/noise ratio via respective delay units forming block output data, which is connected to output of analysis unit for signal/noise ratio. Second inputs of complex mixer are connected to digital local oscillator.

EFFECT: technical result is increasing noise immunity of receiving messages and determining quality of communication channel by adding channel or connecting with best signal/noise ratio.
