摘　　要：论述了FCC发射功率的标准对具有任意chip-duty的DS-UWB通信系统的影响。研究了一个确定了峰值功率谱密度约束的情况,分析了影响平均传输功率的主要因素,从仿真结果可以看出低于最小chip-duty的情况下平均传输功率不能随着带宽的增大而增大,随着带宽的增加,系统容量的增加量减小。FCC established rules regarding UWB transmission systems, Impact of emission constraints on DS-UWB communications that use arbitrary chip-duty is discussed in this letter. Simulation results show that, average emission limit depending on the communication pulse shape and peak-to-average ratios, a minimum chip-duty below which average emission cannot be increased with bandwidth due to the peak constraint is pointed. It is shown that a peak constraint slows down the capacity increment with bandwidth.

关 键 词：超宽带 功率限制 chip-duty 容量
