| 摘要: |
| 随着对混沌理论的深入研究,混沌具有的优良特性必然被人们所认识,并应用到实际工程中来。短短十几年,混沌通信系统得到了充分的发展,目前正从理论分析向实用化转变。混沌通信系统是传统通信系统的扩展,同样可以分为相干通信和非相干通信两大类。文中着重对相干、非相干混沌数字通信系统进行介绍和评价,指出混沌数字通信系统亟待解决的若干问题,最后对混沌在传统通信系统中应用的前景进行了展望。 |

| Abstract: |
| Due to the advantages of chaotic signal, it is becoming promising carrier in communication systems. Now it is transferring from theory research to engineering applications. Chaos-based communication systems are the extension of conventional communication systems and can be broadly classified to two groups: coherent and non-coherent communication systems. This paper mainly discusses chaos-based digital communication systems and evaluates their performance. Some problems about chaotic communications are studied. Finally this paper concludes with a brief discussion on the possible research directions and challenges of employing chaos-based digital communication systems. |
