METHOD FOR SHAPING NOISE-LIKE RADIO PULSES FOR TRANSMITTING BINARY DATA CHARACTERS BY COMPOSITE SIGNALS Russian patent published in 2004 - IPC

Abstract RU 2231924 C1

FIELD: radio engineering; data transfer systems.

SUBSTANCE: proposed method is characterized in that minimal code-frequency modulation of carrier frequency is effected by adding amplitude- and phase-modulated waves of quadrature channels whose modulating code sequences are obtained by re-coding code sequence of noise-like radio pulse, sum obtained is gated by video pulse equal to length of code sequence, opposing signal is shaped by code inversion with aid of modulating code sequence of one of quadrature channels.

EFFECT: enhanced noise immunity of data transfer system.
