WIRELESS TRANSMISSION SYSTEM AND DISTORTION COMPENSATION METHOD

摘要

A wireless transmission system includes a base station device connected to a wireless device by an optical transmission member. The base station device includes an acquiring unit that acquires a distortion component that corresponds to a level of a transmission signal, an amplifying unit that amplifies the distortion component at a predetermined gain, and a transmitting unit that transmits the transmission signal and the amplified distortion component in a separable manner. The wireless device includes a receiving unit that receives the transmission signal and the distortion component, a filtering unit that filters the transmission signal, an attenuating unit that attenuates the distortion component at a gain inverse of the predetermined gain, a combining unit that combines the filtered transmission signal with the attenuated distortion component to obtain a combined signal, and an amplifier that amplifies the combined signal.

1. A wireless transmission system in which a base station device is connected to a wireless device by an optical transmission member, wherein
the base station device comprises
an acquiring unit that acquires a distortion component that corresponds to a level of a transmission signal,an amplifying unit that amplifies the distortion component acquired by the acquiring unit at a predetermined gain, anda transmitting unit that transmits, to the wireless device via the optical transmission member, the transmission signal and the distortion component amplified by the amplifying unit in a separable manner, and the wireless device comprises
a receiving unit that receives the transmission signal and the distortion component transmitted by the transmitting unit,a filtering unit that filters the transmission signal received by the receiving unit at a predetermined frequency band,an attenuating unit that attenuates the distortion component received by the receiving unit at a gain inverse of the predetermined gain used by the amplifying unit,a combining unit that combines the transmission signal filtered by the filtering unit with the distortion component attenuated by the attenuating unit to obtain a combined signal, andan amplifier that amplifies the combined signal obtained by the combining unit.
