摘要
将混沌映射应用于UWB-IR通信系统,可以增强该通信系统的军事通信抗截获能力,但是,其对应的多进制脉位调制的性能公式,只有数值解而无精确的解析解。通过公式推导和对此公式分段积分的近似解析方法,利用M atlab编程实现了其误比特率解析计算过程。而且,通过与数值解的比较,讨论了此解析计算方法的可行性。
The low probability of interception in UWB-IR military communications can be enhanced by applying chaotic mapping technology. However, the BER performance of this UWB-IR M-PPM only has results of numerical computing. This paper deduced the BER theory and realized the analytic computing of the BER under the circumstance of the Matlab software by using a multi-step integral method. Furthermore, this paper compared the analytic results with the numerical results and discussed the feasibility of our analytic method.
