GENERAL-PURPOSE DEMODULATOR Russian patent published in 1999 - IPC

FIELD: radio engineering. SUBSTANCE: demodulator which receives symbol with analog signal, has two inexpensive analog-to-digital converters for sampling of channel signal I and Q with speed which is equal to symbol transmission rate. Carrying unit which receives output signals of converters and digital signal which represents correction of frequency and phase of input signal of demodulator operates as digital unit calculating rotation of coordinate system in order to generate channel digital signals I and Q with error correction compensation. Digital phase shifting unit receives at least one of digital signals I and Q and controls sampling of input signal which is performed by converter. EFFECT: increased functional capabilities of demodulator and receiver. 22 cl, 9 dwg
