FIELD: wireless communication systems; two-mode communication systems.
SUBSTANCE: proposed receiving system using zero intermediate-frequency architecture has antenna, direct converter for converting received radio-frequency signal into modulating-frequency band signal, analog-to-digital converter, variable-gain digital amplifier, accumulator for calculating mean power of amplified modulated-frequency band digital signal within time period, controller for receiving mean calculated power of mentioned signal arriving from accumulator and for maintaining mean power at constant preset value, as well as digital demodulator.
EFFECT: reduced number of components and space requirement.
