An optical/electrical converting portion 150 in an optical receiver 102 optical/electrical-converts the optical signal OS transmitted through the optical fiber 140, to directly obtain a baseband signal SBB.

Abstract: Radio base stations subject each code-division multiplex signal to frequency conversion so as to vary each frequency thereof according to the radio base stations and then converts the signal to an optical signal before transmitting the same to a switching station. The switching station multiplexes the optical signals, subjects a signal obtained after multiplexing to optical-electrical conversion, and extracts the code-division multiplex signal from the respective electrical signal obtained after the conversion. Consequently, each signal to be demodulated by demodulating sections includes nothing but the code-division multiplex signal outputted from the radio base stations. Therefore, a code-division multiplex signal outputted from a desired base station is not disturbed by code-division multiplex signals outputted from the other stations as a noise as will be in a conventional system.

Abstract: A signal including an RF signal and a code division multiple access signal is transmitted so that, in relation to both of the RF signal and the code division multiple access signal, a receiving end can obtain a signal having sufficiently larger power as compared with noise and with no distortion. In order to attain this object, a separation part separates the signal into the RF signal and the code division multiple access signal at a sending end. An amplification part amplifies the RF signal with an amplification factor related to its power. An amplification part amplifies the code division multiple access signal with an amplification factor related to its power. A combination part combines the amplified RF signal and the amplified code division multiple access signal with each other.

Abstract: In FIG. 5, a plurality of signal sources 21.sub.1 to 21.sub.N each generate a carrier with different frequencies. A pulse signal generating portion 23 generates a pulse signal with the same period and time width as those of a horizontal synchronizing signal in NTSC system color television broadcasting. Delay devices 32.sub.1 to 32.sub.N delay timing of the pulse signal for a randomly predetermined delay amount. Level adjuster 52.sub.1 to 52.sub.N generate a modulating signal by adjusting each pulse base of the delayed pulse signal for a level within a range between 12.5% and 74.375% with respect to a pulse top. Modulators 42.sub.1 to 42.sub.N output a signal obtained by modulating the carrier with the modulating signal. A multiplex portion 24 multiplexes the modulated signals to output a resultant signal as a test signal. The error rate of a QAM signal is evaluated with the test signal.

Abstract: An AM signal source frequency-multiplexes and outputs a plurality of AM signals. A soft clipper, which is formed by an amplifier or the like, nonlinearly loosely limits a large amplitude portion (impulsively changed portion) of the frequency-multiplexed AM signal by using its saturation property. Thereafter, an attenuator performs level adjustment for setting the signal at a prescribed degree of optical modulation. On the other hand, a 16QAM signal source frequency-multiplexes and outputs a plurality of 16QAM signals having different carrier frequencies. A frequency multiplexing part further frequency-multiplexes the AM multiplex signal with the 16QAM multiplex signal. An optical transmitter intensity-modulates a laser output beam with the frequency multiplex signal from the frequency multiplexing part and transmits the same. No clipping distortion occurs at this time. An optical signal from the optical transmitter is transmitted to a receiving system through an optical fiber member and is demodulated.
