摘要： A diffusion code generating method for a code division multiplex communication by a spread spectrum system is provided. A receiving apparatus according to the above method receives the signal which was multiplexed by using a plurality of sets of diffusion codes and comprises: a generator to generate a sync code and a plurality of sets of diffusion codes other than the sync code; a correlator to obtain a correlation between a reception signal and the sync code generated from the generator; and a receiver to receive the reception signal on the basis of the plurality of sets of diffusion codes generated from the generator. The generator generates the sync code in a manner such that the cross-correlation values are set to very small values at positions near a code sync point or are enough smaller than the autocorrelation peak of the sync code or are set to very small values at both of or either one of the positions before and after the code sync point.

The reproducing circuit has an operation circuit to arithmetically operate the reception signal and the diffusion code and a detection circuit to detect a difference between the phases of an output of the operation circuit and an output of an oscillator. The oscillator oscillates at a carrier frequency in accordance with a phase difference detected by the detecting circuit.

摘要： 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.

摘要： In a communication system that includes a control station and dependent stations, the control station broadcasts data intended for the dependent stations on a per-superframe basis. The dependent stations relay the data received from the control station among themselves. If a dependent station has received the data transmitted from the control station, the dependent station transmits an acknowledgement response. If a dependent station does not receive an acknowledgement response from another dependent station, then the dependent station relays the data intended for the other dependent station.
