SYSTEM FOR RADIO COMMUNICATION WITH CONTROLLED OBJECTS Russian patent published in 2015 - IPC H04B1/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to electrical and radio engineering and can be used in security systems and systems for monitoring the state of controlled objects. The system includes N≥1 territorially spread-apart receiving stations, from the outputs of which information signals are transmitted via additional links to corresponding inputs of a central surveillance panel, where in each receiving station, an antenna is made in the form of two spaced-apart antenna elements which are connected through antenna amplifiers to the first and second inputs of a two-channel receiver, the first and second outputs of which are respectively connected to the first and second inputs of a digital signal processing unit, the output of which is connected to the input of a secondary digital signal processing unit, the output of which is connected to the input of a data transmitting unit, the output of which is the output of the receiving station.

EFFECT: high stability of operation in dense urban development conditions with high level of industrial noise and interference fading, caused by the multipath effect of signals reflected from urban structures.
