摘要：A spread spectrum communications system includes at least one
communication station for transmitting a plurality of digital information data sequencesvia a plurality of communication channels by using the same PN code sequence. Thecommunication station spreads the respective digital information data sequences by thePN code sequence to provide spread spectrum signals, modulates the spread spectrumsignals by respective carriers having different frequencies from each other to providemodulated signals, and then transmits the modulated signals via the communicationchannels respectively. A frequency interval of the carrier frequencies is determined to aneven-numbered multiple of a symbol rate of the transmitted digital information datasequences.
