FORMATION METHOD OF SYNCHRONISATION PULSES AT RECEPTION OF DIGITAL SIGNALS Russian patent published in 2012 - IPC G06F1/04 

FIELD: radio engineering.

SUBSTANCE: after signals are received, they are converted to units with fixed number of N₀ data, which are divided with markers; synchronisation pulses M_amp, where M_amp - temporary position of actual marker, are generated. For M_amp there counted is -k₁N₀, -(k₁-1)N₀, -(k₁-2)N₀, … N₀, N₀, 2N₀, …, (k₂-1)N₀, k₂N₀ data, where N₀ - fixed number of data in data unit, and k₁ and k₂ - integer numbers of 1 and higher. For each synchronisation pulse M_amp there marked are counting boundaries with the corresponding signals with similar amplitude M_"мним" (-k₁), M_"мним" (-k₁+1), M_"мним" (-k₁+2), …, M_"мним" (-1), M_"мним" (1), M_"мним" (2), …, M_"мним" (k₂-1), M_"мним" (k₂). The above signals and M_amp are amplified and their amplitudes are added. Each total amplitude is compared to the specified threshold and in case the threshold is exceeded for each total signal amplitude, regenerated synchronisation pulse M_reg is shaped. M_reg is introduced for each data unit as to temporary location of the corresponding synchronisation pulse M_"мним" or M_amp. Synchronisation pulse M_amp is removed when M_reg corresponding to it is not available.

EFFECT: improving interference resistance.
