FIELD: information technologies. ^ SUBSTANCE: at each cycle of searching, counts of quadrature components of an input noise-like signal are accumulated at clock intervals, memorised, 4N counts of quadrature components of the input noise-like signal Z1k and z2k are generated. The sign double-stage approximation of the quadrature reference video signals Ik and Qk shape is carried out, results of quadrature components z1k and Z2k multiplication are combined in pairs with counts of approximated quadrature reference video signals Ik and Qk, 2N counts of quadrature components of mutual correlation function are calculated. N values of this function module are separated, the value of the code sequence element delay is identified to set synchronism of a code generator with the received signal. ^ EFFECT: reduction of time required to search for noise-like signals at high noise-immunity of reception. ^ 2 dwg |
