A base station apparatus includes at least one remote unit apparatus including at least one antenna; and a central unit apparatus connected to each remote unit via a transmission path. The remote antenna receives a wireless transmission signal from at least one wireless terminal including at least one antenna. The remote unit includes a channel estimation unit functioning between the terminal antenna and the remote antenna, using a reception signal received by the remote unit antenna; a reception signal processing unit that detects a reception signal corresponding to the transmission signal, using the channel information estimated by the channel estimation unit; a decoding unit that decodes each signal detected by the reception signal processing unit; and an inter-unit transmission unit that transmits each signal decoded by the decoding unit to the central unit. The central unit is provided with an inter-unit receiving unit and a signal selection unit.
