ABSTRACT:
A spread spectrum communication system produces a reference signal. A plurality of message signals are produced. Each message signal has message data. The reference signal and the plurality of message signals are combined as a combined spread spectrum signal. The combined spread spectrum signal is received. The reference signal is detected within the received combined spread spectrum signal. The message data of the plurality of message signals is recovered using the reference signal.
