DEVICE FOR FINDING NOISE-LIKE SIGNAL Russian patent published in 2007 - IPC H04B1/10 

FIELD: radio engineering, possible use in satellite communication systems.

SUBSTANCE: in accordance to method, input noise-like signal is found during two stages. At first stage, serial-parallel search of synchronization pseudo-random series signal is performed, and at second stage - parallel-serial search of signal of pseudo-random information series. Parallel-serial search for signal of synchronization pseudo-random series is performed by three groups of correlators, namely: left, right and central. Number of correlation channels in left and right groups of correlators is even and equal to n. number of correlation channels in central group is equal to three. Realization of commutation of signals of pseudo-random series and pseudo-random information series allows synchronization of device in mode for receiving information of pseudo-random information series by signal of pseudo-random information series with large base. Introduction of time limit to searching for pseudo-random information series provides for transition of searching device to pseudo-random series mode in case of false detection.

EFFECT: shorter time needed to find signal of pseudo-random information series for large bases, increased resistance to interference, decreased probability of false detection of signals.
