METHOD AND APPARATUS FOR RECEIVING BINARY OFFSET CARRIER MODULATED RADIO-NAVIGATION SIGNAL Russian patent published in 2012 - IPC G01S5/14 

Abstract RU 2446412 C2

FIELD: physics.

SUBSTANCE: invention relates to reception of a navigation signal with modulated carrier frequency fp, subcarrier frequency fsp and pseudorandom code with frequency fc, wherein said radio signal is converted to the main bandwidth in two channels I, Q. The receiver and method are characterised by that, a modified code generator (23) performs local generation of K modified pseudorandom codes, where =α.fsp/fc where α is a give whole number, where each of the modified codes has on a time interval Tk, where Tk=l/α.fsp, the form of a pseudorandom code without a subcarrier and is time-shifted with respect to the previous modified pseudorandom code by a value Tk, where in each channel, the signal is multiplied by K modified codes and corrected in phase and quadrature using two locally generated in-phase and quadrature subcarriers.

EFFECT: low consumption of computational and energy resources.
