A radio communication apparatus for performing radio communication, including: a first interface conversion unit which extracts a first signal and a second signal multiplexed and input, and corresponding to two different formats, and combines the extracted first and second signal; and a common amplifier which is shared by the first and second signal by amplifying the combined first and second signal, wherein a signal output from the common amplifier is transmitted.

Radio communication apparatus, radio communication system and radio communication method

A receiving apparatus in a wireless communication system that involves both data transmission using a virtual transmission path in which a plurality of wireless lines of which modulation method is variable are virtually consolidated into one, and time-division multiplex transmission, includes a releasing unit that releases, when a failure occurs in a current line used in the time-division multiplex transmission, one wireless line in the plurality of wireless lines constituting the virtual transmission path from the virtual transmission path; a demodulation unit that changes a modulation method used for demodulation of the one wireless line released from the virtual transmission path by the releasing unit to a modulation method used in the time-division multiplex transmission; and a switching unit that switches line connection from the current line in which the failure has occurred to the one wireless line of which modulation method has been changed by the demodulation unit.
