Abstract
The present invention is a spread spectrum communications system where the plural pseudonoise codes are switched such that one pseudonoise code represents binary "1" and another pseudonoise code represents binary "0" of the binary data to be transmitted. Further, in the receiver, a reference pseudonoise code is generated which is asynchronous with respect to the carrier and with respect to the pseudonoise codes of the transmitter. The reference pseudonoise code is used in a convolver to reproduce the transmitted information signal.
