Patent ID: 7672285

Claim:
A method for minimizing co-channel interference in a communication system, the method comprising the steps of: assigning a first scrambling sequence with a scrambler at a transmission station in the communications system, associated with a header or a pilot sequence of a first frame, to a first co-channel; and assigning a second scrambling sequence with the scrambler at the transmission station in the communications system, associated with a header or a pilot sequence of a second frame, to a second co-channel that is adjacent to the first co-channel, wherein the scrambling sequences are based on Gold sequences with correspondingly different seeds, and the co-channels are among 17 co-channels, the seeds corresponding to the 17 co-channels are specified by Table A or Table B: TABLE A Seed X Co-channel # Decimal Hex 1 1 00001 2 42348 0A56C 3 55204 0D7A4 4 57415 0E047 5 74129 12191 6 88022 157D6 7 111487 1B37F 8 112625 1B7F1 9 123876 1E3E4 10 137205 217F5 11 145515 2386B 12 151841 25121 13 166238 2895E 14 174767 2AAAF 15 183101 2CB3D 16 186848 2D9E0 17 188914 2E1F2 TABLE B Co- Seed X channel # Decimal Hex 1 13 0000D 2 53 00035 3 70 00046 4 74 0004A 5 126 0007E 6 159 0009F 7 179 000B3 8 216 000D8 9 236 000EC 10 238 000EE 11 244 000F4 12 262 00106 13 278 00116 14 536 00218 15 628 00274 16 737 002E1 17 771 00303 wherein non-header portions of the frames are scrambled according to the respective different scrambling sequences.
