RELAY DEVICE AND RELAY METHOD

摘要

Provided is a relay device which is capable of achieving the improvement of error rate characteristics and the reduction in delay amount. In this device, a first conversion unit (201) converts a signal from a time domain to a frequency domain. A signal extraction unit (202) extracts common channel information included in the signal which has been converted by the first conversion unit (201). A signal substitution unit (207) restores the common channel information which has been extracted by the signal extraction unit (202). An addition unit (208) substitutes the common channel information which has been restored by the signal substitution unit (207) for the common channel information included in the signal which has been converted by the first conversion unit (201). A second conversion unit (209) converts the signal including the common channel information substituted, which has been converted by the first conversion unit (201), from the frequency domain to the time domain.
