摘　　要：在DCSK系统多址方案研究的基础上,提出了一种新的跳时多址的实现方案。分析了系统的信号和系统的性能,重点分析了在高斯白噪声信道中的特性,推导并给出了误码率公式和系统仿真结果。从理论上证明了跳时多址DCSK系统与其他多址方式相比具有更低的误码率。The article,based on the study of multiple access schemes for DCSK system,proposes a new time-hopping multiple access scheme for DCSK system,and then analyzes the system signal and performance,particularly the characteristics of the system in white Gaussian noise channel.The formula for bit error rate is derived and system simulation result is presented.It is proved theoretically that the time-hopping multiple access DCSK system has lower BER than DCSK systems with other multiple access schemes.
