Problem statement. The use of broadband signals (BBS) at the first level of the transport network, as a specific mechanism for encrypting the traffic flow, presupposes effective processes for their search, capture and synchronization, counteraction against synchronization failure, unauthorized access to the communication channel and information flow, and various kinds of network interference. The solution of these problems is associated with the use of the appropriate types of BBS (recurrent sequences, pseudorandom sequences), procedures, methods, protocols that will provide the required quality of service in conditions of active electronic warfare and information confrontation. Therefore, the development of methods for searching for the synchronization of such BBS that meet these requirements is a very urgent modern problem.

Goal. Development of a new method for accelerated search and effective synchronization of BBS, which are phase-shift keyed double derivatives of nonlinear recurrent sequences (D DNRS), which have the above distinctive positive properties and characteristics that allow it to be implemented within the framework of the theory of the «third decision scheme».

Results. The results of the development of a new method for searching and synchronizing BBS in the form of DNRS, which implements the principles of the «third decision scheme» of receiving DNRS and provides a significant increase in the efficiency of search and synchronization of BBS, are presented.

Practical relevance. The developed method for searching and synchronizing BBS in the form of DNRS can be used in the construction of promising packet radio networks.
