Filed: 1990-06-06
Granted: 1995-06-13
Abstract: A system for removing line deterioration elements such as intersymbol interference, carrier frequency offset and phase jitter, etc. from the receiving signal.  An automatic equalizing means (10) compensates for signal deterioration by intersymbol interference.          Next, a carrier phase control means (12) compensates for signal deterioration by carrier frequency offset.          Thereafter, a phase jitter interference removing means (18) allows increase of only phase jitter element by utilizing line characteristic to easily extract phase jitter element.  Since the signal including phase jitter is a low frequency signal, a phase jitter removing means (14) further removes phase jitter by shifting the frequency range to a higher frequency range on the frequency axis and then shifting it to the bandwidth for each processing.
