| Abstract: | The paper makes analysis and comparisons on the correlation characteristic and the balance characteristic of the m-sequence,Gold-sequence and one-dimensional Logistic sequence. Then a new complex spread-spectrum sequence is presented. The experimental results show that the Chaotic sequence has better performance than the PN sequence has,so it has the better performance in anti-jamming and privacy. |
