Orthogonal digital signals arose considerable interest among the known signal systems, since such signals distinction can be carried out with the highest reliability. Theoretical bases of construction of orthogonal digital signals, evaluation of the ensemble, correlation and structural properties are presented. The requirements for the choice of generating signals are formulated. Expediency of construction of the systems of derivatives of signals through the use of non-linear digital signals (characteristic sequence, cryptographic sequence) to improve noise immunity performance, noise immunity, stealth operation and data information security in secure telecommunication systems is proved.
