| 1. A method for minimizing co-channel interference in a communication system having at least a first signal and a second signal,
each signal transmitted on different channels within the communication system, comprising:
scrambling a first frame using a first scrambling code;
attaching a first header to the first frame to create the first signal;
scrambling a second frame using a second scrambling code;
attaching a second header to the second frame to create the second signal; and
simultaneously transmitting the first signal and the second signal, from the same transmitter, over different channels of
the communication system.
