摘要

在目前的文献中，传输参考系统的延迟线(DL)被认为是理想的。然而，实际上不可能设计出具有完美相频特性的DL。本文基于非理想DL的群延迟纹波(GDR)统计模型，研究了TR超宽带通信系统平均误码率(BER)的退化问题。通过蒙特卡罗仿真，验证了不同TR超宽带信道环境和不同信噪比条件下GDR幅值对误码率性能退化的影响。

The impact of group delay ripple for TR UWB communication system

In the present literature, the delay line (DL) in transmitted-reference (TR) system is supposed to be ideal. However, it is in fact impossible to design a DL with perfect phase-frequency characteristic. In this paper, based on the statistical model of group delay ripple (GDR) of the non-ideal DL, we investigate the degradation of average bit error rate (BER) for TR UWB communication system. Through Monte Carlo simulations, the impact of GDR amplitude on the degradation of BER performance under different TR UWB channel environments and different SNR conditions is verified.
