摘　　要：本文提出一种基于差分混沌频率调制(FMDCSK)的快速跳频扩谱通信系统(简称FFH-FMDCSK)。它不但可以解决FMDCSK系统的抗干扰和多址接入问题,而且还可以提高其抗多径衰落的能力,同时降低对其他系统的干扰。本文比较了FFH-FMDCSK和FMDCSK在多径信道下的系统误码率,给出他们的理论公式和Monte-Carlo仿真结果。A new chaotic spread spectrum communication system FFH-FMDCSK is presented, which is based on FMDCSK and fast frequency hopping techniques. FFH-FMDCSK is able to improve the performance of FMDCSK on anti-jam, multiple access, and resistance to multipath fading as well as low interference to other systems. This paper compares the BER performance of FFH-FMDCSK with that of FMDCSK in multi-path channel, and delivers the theoretical analysis and Monte-Carlo simulation results.
