摘要： Each of first radio communication devices includes; a frequency spread unit which spreads frequency of a transmitted signal to generate a frequency-spread signal; and a mapping unit which allocates the frequency-spread signal to a subcarrier according to the mapping information which specifies a subcarrier. A second radio communication device includes: a demapping unit which extracts from a received signal a signal of the subcarrier specified by the mapping information; and an inverse frequency spread unit which inverse-frequency-spreads the extracted signal. The first radio communication device or the second radio communication device includes a use subcarrier decision unit that decides a subcarrier to which the frequency-spread-signal is allocated according to a communication path capacity of each subcarrier of each antenna used for transmission by the first radio communication devices and generates mapping information used to specify the decided subcarrier.
