    Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication system, receiver, and transmitter, for reducing the operating time of a reception circuit of the receiver even if there is a clock error between the transmitter and receiver, thereby reducing power consumption. SOLUTION: In a conventional method as shown in Fig.1(A), the receiver is started earlier by a time Tm and synchronization is established before a clock error in the receiver does not exceed the time Tm, so that excessive reception time is required for clock synchronization, thereby hindering a reduction in power consumption in the receiver. As shown in Fig.1(B), a synchronization signal is sent several times in succession in a short time from the transmitter, and the receiver receives only one synchronization signal transmitted in succession. Consequently, reference clocks can be synchronized by starting the receiving operation of the receiver earlier only by a time Tm' (Tm'≤Tm). COPYRIGHT: (C)2010,JPO&INPIT
