摘要
文章中,我们分析了基于多波形的超宽带传输参考脉冲无线电系统的性能。在不考虑帧间干扰和多径干扰的情况下,我们得出了误符号率的闭式解。接着我们又讨论了多波形传输参考系统的抗帧间干扰能力。通过对比仿真结果,我们发现在有帧间干扰的环境中,多波形传输参考系统能够达到比单波形系统更好的误码率性能。
In this paper, we analyze the performance of transmitted-reference(TR)impulse radio(IR)system with multiple pulse types. We obtain the exact expression of symbol error probability(SEP)without considering of the inter-frame interference(IFI)and multiple access interference(MAI). Then we discuss the capability of multi-pulse TR-IR system against the IFI. By observing the result of simulation, we find that the multi-pulse TR-IR system can achieve better BEP performance than the conventional single pulse system in the IFI environment.
