Abstract
A repeater converts a frequency of a received signal based on a local oscillating frequency and transmits a transmitting signal of a frequency that is different from the frequency of the received signal. Here, the local oscillating frequency includes a local oscillating error that may be different in a plurality of repeaters. Accordingly, the repeater cancels the local oscillating frequency error itself in a frequency conversion so that transmitting frequencies between the plurality of repeaters may be identical.
