RÉSUMÉ

Information systems advance and improve rapidly. And as far as the requirements for such systems increase the synchronization requirements also rise. Linear recurrence sequences are commonly used in information systems for synchronization. This paper deals with a synthesis of filtering algorithms of such sequences. The synthesized algorithms can be classified as subincoherent (quasi-noncoherent) algorithms as opposed to incoherent ones that use averaging over the entire region of phase ambiguity, or quasi-coherent algorithms, which use phase estimate of the received signal. The results of computer simulation of synthesized algorithms for various signal-to-noise ratios and accumulation time are presented.
