Abstract

Known are multi-branch and interpolation quadrature receivers in which a quantised phase signals having a given phase resolution are fed to a phase-sensitive demodulator reconstructing the data from pulses generated at phase level passings. To avoid unacceptable data jitter, the phase resolution has to be considerable. Herewith, the known receiver becomes complex and/or is not satisfactory as to power consumption. A quadrature receiver is proposed that is very accurate and that has reduced power consumption. To this end, in the quadrature receiver data signal reconstruction instants are determined at predetermined instants between successive demodulation pulses of opposite polarity, and data is outputted at these instants. The predetermined instants are chosen in accordance with the used modulation method and/or transmission parameters.
