Patent ID: 8462875

Claim:
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, wherein the reference clock generating unit includes an electric power converting unit that converts the baseband signal into the electric power, a cyclic adding unit that includes a plurality of information holding units, adds a value obtained by multiplying an oldest piece of information out of pieces of information held by the information holding units by an oblivion coefficient to the electric power, and replaces the oldest piece of information with a result of addition, an information detecting unit that, for every predetermined period, detects a maximum value from among the pieces of information held in the information holding units and rank order information indicating a rank order at which the maximum value is obtained as the result of addition, and a clock generating unit that generates the reference clock based on the rank order information.
