摘要
PURPOSE: A wireless transmission system based on an optical fiber is provided to supplement the input loss of the modulation by an optical signal amplification of semiconductor optical amplifier. CONSTITUTION: A harmonic generator(140) generates a frequency of an optical signal for DL(DownLink) transmission or an optical signal for UL(UpLink) transmission and a harmonic waves of the signals according to a sub harmonic frequency. A field absorption modulator(142) converts the optical signal for DL(DownLink) transmission and the optical signal for UL(UpLink) transmission into the DL transmission data signal and the UL transmission optical signal. A DL signal processor(144) performs power amplification and noise removal about the UL transmission data signal. An UL signal processor(146) removes noise of the UL transmission data signal.
