| 摘 要： | 文中对工作在多径有噪信道内的DS-UWB通信系统进行了分析,为DS-UWB通信系统的进一步研究提供理论参考.通过分析DS-UWB通信系统接收信号组成,给出多径分量引起干扰值的统计表示.得到了扩频码正交性保持情况下系统误码率的理论公式,并结合IEEE UWB信道模型进行了Matlab仿真.仿真结果显示,该理论公式能较好地反映影响DS-UWB通信系统误码率的各种因素,分析结果与实际情况基本吻合.

| Abstract: | In order to provide theoretical reference for advanced research of DS-UWB system, this paper analyzes the DS-UWB system over multipath AWGN channel. By analyzing the components of the DS-UWB received signal, it gives the statistic characterization of multipath interference. A theoretical formula for the error probability of DS-UWB system is proposed in case that the orthogonal codes are kept. Matlab simulation is implemented in combination of the IEEE 802.15 UWB channel model. Simulation results indicate th... |
