| Abstract: | The paper introduces the principle of the frequency-hopping spreading-spectrum communication system, and provides two methods of generating digital chaotic sequences from the Chebyshev chaotic map. Then it proves their suitability for spread frequency code by comparing their sequences. Meanwhile a spreading-spectrum communication system is built to simulate it and prove its validity. |
