Most modern broadband system (MBS) working in the ultra short wave frequency range using complex signals type of discrete-frequency signals (DFS). Simultaneous increase skrytnostnyh characteristics and noise immunity of the NLS, together defining MBS immunity can only be achieved by simultaneously increasing the base DFS and volume of the ensemble systems these signals. Hence, to meet the existing requirements to the characteristics of modern MBS, are invited to apply in these MBS DFS derivatives by type of double coded discrete-frequency signals (DDCDFS). The basis of the formation of advanced DDCDFS with desired properties make up double derivative control numeric code sequences (DDCNCS). Properties DDCNCS reflect the properties formed on the basis of their DDCDFS. Therefore, the analysis of the structural properties of the ensemble and DDCNCS (in order to achieve the above object) is an important task.

As part of this task in the article describes the theoretical bases of formation DDCNCS in the amount entered: definitions, mathematical and structural model of formation DDCNCS based accounting features and use of elements of the multiplicative groups of Galois fields, new types of determinism «thin» DDCNCS internal structure. Obtained results of the evaluation length DDCNCS. Quoted in tabular form the results of research obtained by the simulation algorithm of formation DDCNCS using a computer in a public register.
