FIELD: communications.
SUBSTANCE: the device combines the possibility to carry out the search of multiple shifts of single pilot signals, such that are found in the system according to standard IS-95, with the possibility to search multiple pilot signals, such that are found in the global system of navigation and position determination system (GPS). Both searches can be accomplished in a single architecture combining the characteristics of parallel computation of the matched filter with the versatility providing for possibility of fulfillment of a variable number of incoherent accumulations at a high rate for a wide range of search hypotheses with an effective use of resources.
EFFECT: parallel use of the structure of the matched filter by the method of separation in time for the search of multiple windows, as well as arbitrary independent demodulation of the Walsh sequence for each search window; in the conditions of temporary separation search for any shift is accomplished.
