| Abstract: | A novel generation method of s pread-spectrum sequences based on spatiotemporal chaotic model-OCML driven by Chua's circuit has been introduced in this paper. The good features of autocorre lation and crosscorrelation of this sequence are also testified. The simulation result shows that it has good spread-spectrum properties and meets the demand o f spread-spectrum sequence in the spread-spectrum communication systems. |
