Abstract
A wireless communication apparatus of the present invention that uses an adaptive modulation radio scheme, includes: two-system transmission paths of an active system transmission path and an auxiliary system transmission path; a line information acquiring unit that acquires line information indicating line states of the active system transmission path and the auxiliary system transmission path; and a signal processing unit that determines whether or not a fault occurs in the active system transmission path and the auxiliary system transmission path, based on the line information acquired by the line information acquiring unit. The signal processing unit performs a setting so as to perform wireless communication using the two-system transmission paths of the active system transmission path and the auxiliary system transmission path, in a case of determining that a fault does not occur in the active system transmission path and the auxiliary system transmission path. The signal processing unit performs a setting so as to perform wireless communication using only the transmission path in which a fault does not occur among the active system transmission path and the auxiliary system transmission path, in a case of determining that a fault occurs in either one of the active system transmission path and the auxiliary system transmission path.
