摘要： A branch portion 107 branches a modulating signal into two signals in opposite phases. One of them is inputted to an FM laser element 102. The other one is adjusted in propagation delay and in amplitude and then is inputted to an IM suppressing laser element 110. The FM laser element 102 outputs an optical-frequency-modulated signal around a wavelength .lambda.1, whose optical intensity is also modulated. A local light source 104 outputs light at a wavelength .lambda.0, which is different from the oscillation wavelength .lambda.1 of the FM laser element 102 by .DELTA..lambda.. The IM suppressing laser element 110 outputs an optical-intensity-modulated signal. The three lights are combined and inputted to a photodetection portion 106. The photodetection portion 106 applies a heterodyne detection to inputted lights to output an FM modulated signal corresponding to a beat signal of the outputted optical signal from the FM laser element 102 and the outputted light from the local light source 104 at frequency corresponding to the difference .DELTA..lambda. between the original two wavelengths, and also cancels the average-value variation component in the FM modulated signal with an electrical signal produced by square-law detecting the optical-intensity-modulated signal from the IM suppressing laser element 110, thereby producing an ideal FM modulated signal.

摘要： A data communication apparatus is highly concealable and significantly increases time necessary for an eavesdropper to analyze cipher text. A multi-level code generation section generates, by using predetermined key information, a multi-level code sequence in which a signal level changes so as to be random numbers. The multi-level processing section combines a multi-level code sequence and information data, and generates a multi-level signal having a level corresponding to a combination of the multi-level code sequence and the information data. In the multi-level code generation section, a random number sequence generation section generates a binary random number sequence by using the predetermined key information. A multi-level conversion section generates a multi-level code sequence from the binary random number sequence in accordance with a predetermined encoding rule.

摘要： To provide a receiving apparatus which is capable of demodulating information data from a multi-level modulated signal, which is generated by using a Y-00 protocol, without using high-performance component parts. In the receiving apparatus, the soft decision section 211 performs soft decision on the multi-level signal 22, in which a fixed decision level is used. A converted data identification section 214 performs logical decision on a value of the converted information data 25 in accordance with a highest-order bit of a multi-level code sequence 23 and a decision result 24 of the soft decision. A data reproduction section 215 performs an XOR operation between the converted information data 25 and a lowest-order bit of the multi-level code sequence 23, and outputs a resultant thereof as information data 23. Accordingly, the receiving apparatus identifies the information data 23 by using only some of the bits of the multi-level code sequence 23, whereby precision requirements for the component parts to be used can be eased.

摘要： A data communication system that enhances concealment by significantly increasing the time required for a wiretapper to decrypt a cipher text. The data communication system is constituted by connecting a data transmitting apparatus (13105) to a data receiving apparatus (11201) via a transmission path (110). In the data transmitting apparatus (13105), a multilevel encoding part (111) receives a predetermined first initial value (key information) and information data and generates a multilevel signal that varies in level substantially in a random number manner. A dummy signal superimposing part (118) superimposes a dummy signal on the multilevel signal. A modulating part (112) converts the multilevel signal to a modulated signal of a predetermined modulation form and transmits the modulated signal. The data receiving apparatus (11201) demodulates the modulated signal to output the multilevel signal, and receives a predetermined second initial value (key information) and the multilevel signal to reproduce the information data.

摘要： Provided is a data communication apparatus which significantly increases time necessary for an eavesdropper to analyze cipher text and which is superior in concealability based on astronomical computational complexity. A multi-level signal, which is generated by using data and key information, has a minor amplitude modulation, which is based on a random number signal generated on a transmission side, overlapped thereon, and is then transmitted. On a receiving side, instead of data decision, three types of decision, i.e., “1”, “0” and “decision impossible”, are performed on a random number signal by using two threshold values whose interval is significantly wider than a modulation amplitude based on random numbers. Information of a bit whose decision is performed successively is returned to the transmission side, and the bit is used commonly as a new key. Accordingly, in a single transmitting/receiving apparatus, cipher text transmission and key distribution can be realized simultaneously.

摘要： Modulators respectively modulate baseband signals into IF signals having different frequencies. A multiplexer multiplexes the IF signals. An electrical-optical converter intensity modulates the multiplexed IF signals into optical signals. A local oscillation signal source outputs a predetermined local oscillation signal. An external modulator intensity-modulates the optical signal using the local oscillation signal. An optical branching portion branches the intensity-modulated optical signal and respectively outputs branched optical signals to radio base stations. An optical-electrical converter converts the optical signal into an electric signal, to obtain an RF signal by frequency-converting the IF signal. An antenna only transmits a component having a desired radio frequency extracted in a band filter from the RF signal to a subscriber terminal. Frequency conversion from the IF signal to the RF signal is thus optically performed, whereby the frequency or electrical-optical converter is shared among the radio base stations.
