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