APPARATUS FOR SPATIALLY SEPARATED RECEPTION OF DIGITAL SIGNALS OF SYSTEMS OF MOBILE RADIO COMMUNICATION Russian patent published in 2020 - IPC H04B1/00 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication engineering and can be used in radio communication systems with mobile and stationary objects using digital types of signal modulation. Systems which adaptively tracking in real time after variation of delay, phase and signal-to-noise ratio and providing optimum summation of digital signals are used. System is based on several coupled PLL loops and an interpolating filter as a delay line. Signal processing includes the following actions, such as delay time alignment in channels based on synchronization of symbol (clock) frequencies, obtaining signal phase coherence based on carrier frequency synchronization and signal weighting based on the signal-to-noise ratio estimate result.

EFFECT: technical result consists in improvement of noise immunity of operation of complex space-diversity reception in conditions of fast changes of parameters of signals of delays, phases and signal-to-noise ratio in receiving channels with obtaining of resultant signal-to-noise ratio.
