We consider the problem of delay acquisition of broadband signals based on a complex code sequences in conditions of high requirements to accuracy and efficiency synchronization. The problem occurs when you select a processing method and circuit implementation to ensure a compromise between speed and complexity of the search devices for long coded sequences.
The purpose of this article is the formal model and the processing method of the subclass of maximum length codes, based on fast transformations in Galois fields using vector-matrix operations, obtaining the functional structure of the double-dwell delay acquisition scheme, and comparative estimation of efficiency schemes such a search towards the optimal.
