摘　　要：为研究带有有限长脉冲响应陷波滤波器(NF)的传输参考型超宽带系统(TR-UWB)的抗窄带干扰性能,在IEEE 802.15.3a建议的标准超宽带信道下,分析比较了在不同参数设置下,该系统自相关接收机的误比特性能。仿真结果表明,带有陷波滤波器的传输参考型超宽带系统能够有效降低窄带干扰,并且系统接收机结构简单,无需信道估计,大大降低了计算量和系统复杂度。The performance for Narrowband Interference（NBI） resistance of Transmitted Reference UWB（TR-UWB） system with a Finite Impulse Response（FIR） notch filter is investigated in this paper. Based on the Ultra Wideband（UWB） channel model proposed by IEEE 802.15.3a study group, the bit error performance of the system autocorelation receiver is analyzed and compared at various system parameters. The simulation results show that the proposed TR-UWB system is able to mitigate the NBI effectively. The system with the simple receiver structure does not need the channel estimation, which reduces the computation and system complexity significantly.
