Abstract
A radio communication system has a transmitter and a receiver that transmits and receives, respectively, synchronization signals. The transmitter has a multiple-synchronization-signal generation section configured to generate the synchronization signals, a radio circuit configured to transmit the synchronization signals in a predetermined transmission cycle from a start time of the predetermined transmission cycle and with an interval shorter than the predetermined transmission cycle, and a synchronization signal sequence number generation section configured to assign a sequence number to each of the synchronization signals. The receiver has a synchronization signal detection section configured to detect any one of the synchronization signals transmitted by the transmitter, and has a clock error correction section configured to correct an error of a reference clock based on the sequence number assigned by the synchronization signal sequence number generation section to the synchronization signal detected by the synchronization signal detection section.
