Annotations languages:

In the article the method of increase of antijammingness of alarm-code constructions is offered with OFDM, based on the use as an alarm base at forming of channel signals of own vectors of subbar matrices with the value of own numbers near to unit. It is rotined with the use of computer design, that his application allows to promote stability to influence of fluctuation, narrowband and impulsive hindrances in 2 times as compared to the classic OFDM signals.
Keywords: OFDM, alarm base, subbar matrix, antijammingness, channel signals, fluctuation hindrance, narrow-band hindrance, impulsive hindrance, efficiency of communication network
