COMMUNICATION APPARATUS, SEMICONDUCTOR INTEGRATED CIRCUIT AND ELECTRONIC DEVICE

Title:

COMMUNICATION APPARATUS, SEMICONDUCTOR INTEGRATED CIRCUIT AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2008/044344

Kind Code:

A1

Abstract:

There are included a calculating part (2) that calculates a correlation value of a predetermined pattern included in a received signal; a generating part (3) that generates, based on the correlation value, a synchronization signal; a determining part (4) that determines a predetermined period with reference to the synchronization signal; and a control part (5) that controls the power consumption of at least one of the calculating part (2) and generating part (3). The determining part (4) defines a first interval, which includes the synchronization signal on the time axis and has a predetermined length, and a second interval that does not overlap with the first interval. The control part (5) controls the power consumption by controlling an electric signal in at least one of the calculating part (2) and generating part (3) during the second interval.
