<p>A reception signal processing system in a communication system (e.g. a modem) for transmitting data under a predetermined baud-rate, including: a first unit (1,2) operated at a first frequency (fs) for receiving the reception signal (Xn) and for recovering loss components in the reception signal; a second unit (3) responsive to an output (Yn) of the first unit, for determining a first ideal reception signal (Rn) corresponding thereto based on a second frequency (fb) corresponding to the baud-rate, the first frequency (fs) being higher than the second frequency (fb); and a third unit (4) operatively connected to the first unit (1,2) and second unit (3), responsive to the first ideal reception signal (Rn) from the second unit (3) based on the second frequency (fb) and for generating and providing a second ideal reception signal (Sn) based on the first frequency (fs) to the first unit (1,2); the second ideal reception signal (Sn) being derived by processing the first ideal reception signal (Rn), and the first ideal reception signal corresponding to the data transmitted. The system is capable of suppressing high-frequency phase jitter in the reception signal (Xn).</p> |
