Abstract

PURPOSE: To reduce the time for a waiting state where the power source of a reception circuit is turned ON by permitting the reception circuit to receive a preamble by inserting a synchronizing code word between a specified power conservation code and the preamble, and thereby making the reception circuit execute the reception operation of a data code.
CONSTITUTION: When the top of the preamble 1 and a timing when power source is turned ON in a state where the reception circuit is intermittently receiving are coincident, the reception circuit receives the preamble 1 during 32 bits until its own power source is turned OFF so as to come into the state of waiting the reception of SC (synchronizing code work) 4 while the power source of the reception circuit is kept ON. After then, SC 6 is received so that the power source starts the reception operation of the data code 5 and is temporarily turned OFF. The power source is turned ON from behind by 160ms to several ms on this side by the falling of SC6. At this time the data code 5 is not transmitted from a transmitter so that reception operation is started by turning OFF the power source. Power consumption is reduced by inserting SC6 between the specified power consumption code 2 and the preamble 3.
