Derangement detector in a receiver of a system for data transmission by means of phase modulation of a carrier |
摘要 |
A receiver of a system for data transmission by means of p-phase modulation comprises a digital phase discriminator with a calculating unit which calculates in a first interval of each sampling period the in-phase and quadrature components of a signal derived from a passband signal at sampling instant jT by a phase rotation over an angle equal and opposite to the phase of a reference carrier at instant (j-1)T.
