FIELD: physics.
SUBSTANCE: there are offered methods of frequency hopping agility with code demultiplexed (CDM) pilot signal within multiple carrier communication system. Each transmitter of the system conveys broadband pilot signal within all the subranges so that the receiver may evaluate total channel characteristic at once. The broadband pilot signal for each transmitter can be generated with using direct-sequence spectrum spreading considering pseudorandom numeric ("ПШ") specified for this transmitter.
EFFECT: ensured possibility of receiver to identify individually and restore multiple broadband pilot signals conveyed by multiple transmitters at once.
