METHOD OF OBTAINING AND RECEIVER FOR RADIO-NAVIGATION SIGNAL, MODULATED BY CBOC PROPAGATING OSCILLATORY SIGNAL Russian patent published in 2011 - IPC G01S5/14 

FIELD: physics.

SUBSTANCE: to obtain a radio a radio-navigation signal which is modulated by a composite oscillatory signal, the composite oscillatory signal contains a linear combination with real-valued coefficients of the component BOC (n₁, m) and the component BOC (n₂, m), wherein n₁ is different from n₂, and correlation is realised between the local oscillatory signal and the composite oscillatory signal during a time interval with duration T. The local oscillatory signal is a binary oscillatory signal generated during the said time interval using at least one segment of the oscillatory signal BOC (n₁, m) and at least one segment of the oscillatory signal BOC (n₂, m). At least one segment BOC (n₁, m) has total duration αT, where the value α lies strictly between 0 and 1, and at least one segment of the signal BOC (n₂, m) has total duration (1-α)T.

EFFECT: obtaining a radio-navigation signal which is modulated by a composite propagating signal.
