【摘要】 超宽带脉冲波形的设计决定了脉冲式的超宽带系统的功率谱是否符合FCC的限制,通过分析ParrB的超宽带脉冲设计算法,提出了直接频域法设计超宽带脉冲,该方法根据脉冲的频域限制设计脉冲的时域波形,并以此方法设计出了一种超宽带脉冲,仿真结果表明,所设计的超宽带脉冲在频谱掩蔽填充效率上优于ParrB脉冲。更多还原

【Abstract】 The UWB pulse determines whether the IR-UWB system meets the power spectral constraint of FCC.After analyzing the Parr B algorithm for designing UWB pulse,this paper presents a new method,the frequency-domain method,to design UWB pulse.It designs UWB pulse expression in time-domain according to its spectral constraint.The frequency-domain method has the flexibility of designing pulses to fit different power spectral constraints.It designs a UWB pulse using the new method.The designed pulse has higher mask-filling efficiency than Parr B pulse.更多还原
