1. A method for determining scrambling codes for reducing co-channel interference in a communication system, comprising:

  • defining at least one initial default sequence;

    generating a scrambling code with a scrambling code generator;

    scrambling a first signal in a plurality of signals with a scrambler apparatus using the generated scrambling code;

    comparing the scrambled first signal with a remainder of the signals in the plurality of scrambled signals meeting a specified co-channel interference criterion with a computer device; and

    saving the scrambling code word in the computer device if the comparison determines that the first signal scrambled with the scrambling code also meets the specified co-channel interference criterion, wherein the specified co-channel interference criterion comprises at least reducing co-channel interference between the first signal and the remainder of the signals in the plurality of scrambled signals.
