DEVICE FOR AUTOMATIC FINDING OF RADIO COMMUNICATION CHANNELS Russian patent published in 2006 - IPC H04B7/22 

FIELD: radio engineering, in particular, engineering of military mobile command centers, also can be used in other industrial branches.

SUBSTANCE: device for automatic finding of radio communication channels contains, serially connected, generator of standard signal, key, receiving block, control block and standard signal analyzer, output and second input of which are connected to input and second output of standard signal generator, second and third outputs of which are connected respectively to second outputs of receiving block and control block, third output of which is connected to another input of key, while fourth output through commutator is connected to receiving block, while third output of standard signal analyzer is connected to another input of control block, and third output of receiving block is connected to third input of standard signal analyzer. Device additionally contains, connected serially, narrowband channels selection block, block for selecting optimal channel and block for selecting optimal shape of signal, and also block for estimating noise-like signal and block for controlling parameters of standard signal, while fourth outputs of receiving block are connected to inputs of block for selecting narrowband channels.

EFFECT: increased precision and decreased selection time for narrowband and broadband radio communication channels in case of presence of interference correlated to signal.
