TIMING REGENERATING DEVICE
First Claim
1. A timing regenerating device that regenerates a process timing for demodulating a reception signal in a spread spectrum communication system, the timing regenerating device comprising:
- a signal extracting unit that extracts a baseband signal from the reception signal on which an inverse spread processing is performed; and
a reference clock generating unit that converts the baseband signal into an electric power and generates a reference clock for a latch timing of the baseband signal output from the signal extracting unit based on the electric power.

Abstract
A timing regenerating device regenerates a process timing for demodulating a reception signal in a spread spectrum communication system. The timing regenerating device includes a signal extracting unit that extracts a baseband signal from the reception signal on which an inverse spread processing is performed and a reference clock generating unit that converts the baseband signal into an electric power and generates a reference clock for a latch timing of the baseband signal output from the signal extracting unit based on the electric power.

6. A timing regenerating device that regenerates a process timing for demodulating a reception signal in a spread spectrum communication system, the timing regenerating device comprising:
-
a signal extracting unit that extracts a baseband signal from the reception signal on which an inverse spread processing is performed; and a reference clock generating unit that obtains a difference between a current baseband signal that is currently extracted by the signal extracting unit and a previous baseband signal that is previously extracted by the signal extracting unit and generates a reference clock for a latch timing of the baseband signal output from the signal extracting unit based on the difference. - View Dependent Claims (7, 8, 9, 10)
