  • Patent number: 6625162
    Abstract: In a communication system including plural communication apparatuses that communicate each other using a single communication path, the state of the communication path is detected for communication. If the communication path is busy, a first control method is performed for controlling access to the communication path using a back off time selected at random. A second control method secures the communication path by transmitting and receiving the predetermined signal at transmission of a signal so as to control access to the communication path. In accordance with the kind of the signal to be transmitted, the first or the second control method is selected for communication. Thus, plural communication apparatuses can perform efficient communication.

  • Patent number: 6616352
    Abstract: A bidirectional optical space transmission system is made up of a pair of optical transmission apparatus. Each optical transmission apparatus comprises a signal generating circuit for generating a pilot signal, a multiplexing section for multiplexing the pilot signal and a main signal to be transmitted, an electrooptic converter section for emitting an optical signal on the basis of the signal produced by the multiplexing process, a light receiving element for receiving an optical signal transmitted from the partner optical transmission apparatus and detecting a pilot signal contained therein, and a demodulation circuit for demodulating the pilot signal detected by the light receiving element. Pilot signals multiplexed with main signals to be transmitted through the bidirectional optical transmission system are subjected to spreading modulation and demodulated for spreading by the demodulation circuit.

  • Patent number: 6459721
    Abstract: A receiving apparatus includes a base-band conversion circuit, a synchronizing circuit/code generator and a demodulator. The base-band conversion circuit converts a received signal into a base-band signal. The synchronizing circuit/code generator detects a spread code included in the received signal to generate a plurality of spread codes in synchronization with the spread code included in the received signal. The demodulator uses the plurality of spread codes supplied by the synchronizing circuit/code generator to demodulate the base-band signal.
