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IEEEUWB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。 In order to provide theoretical reference for advanced research of DS-UWB system, this paper analyzes the DS-UWBsystem over multipath AWGN channel. By analyzing the components of the DS-UWBreeeived 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 UWBchannel model. Simulation results indicate that various the factors affecting the performance of DS-UWB communication system can be revealed by using the proposed formula, and also the formula is effective.
