A signal transmitting apparatus for an optical base station is disclosed. According to the invention, a base station outputs a digital IQ signal to an optical connecting unit. The optical connecting unit processes the digital IQ signal digitally, and transmits the digital signal over an optical network to a remotely located optical base station. The remote station digitally processes the signal before converting to an RF signal for transmission. The invention advantageously decreases signal loss and noise associated with analog processing in the optical connecting units and remote stations in the related art. System reliability is also improved.

According to a digital linearizing method, a digital input signal on a first path is operated with an output signal of a main amplifying unit, to thus detect distortion components included in the output signal of the main amplifying unit. A digital input signal on a second path is correlated with the detected distortion components, to thus adaptively control a gain of the digital input signal on the second path during the detection of the distortion components. Therefore, according to the above method, it is possible to effectively and correctly remove the distortion components included in the output signal of the main amplifying unit by amplifying the detected distortion components and coupling the amplified distortion components with the output signal of the main amplifying unit.
