摘要

本文比较了室内超宽带(UWB)信道的时域(TDE)和频域均衡(FDE)技术。这项工作的创新之处在于采用了重叠保存方案，与循环前缀不同，它保证了发射机电路不发生变化。根据(Cassioli et al.， 2002)提出的模型对该通道进行了模拟。基于我们的仿真结果，我们表明基于128点FFT/IFFT的FDE，重叠保存长度为64，具有最优的性能。结果还表明，在给定的场景中，FDE和TDE的性能有些相似。然而，由于TDE的计算复杂性，它并不是一个可行的解决方案。因此，我们建议在室内超宽带系统中使用具有上述参数的FDE。

Comparison of time domain and frequency domain equalizers for indoor UWB systems

In this paper we compare time domain (TDE) and frequency domain equalization (FDE) techniques for an Indoor Ultra Wide Band (UWB) channel. The innovation in the work is the employment of Overlap Save scheme, which unlike Cyclic Prefix guarantees no change in transmitter circuitry. The channel has been simulated according the model proposed by (Cassioli et al., 2002). Based on our simulation results, we show that a 128 point FFT/IFFT based FDE with an overlap save length of 64 gives the most optimal performance. The results also show that FDE and TDE give somewhat similar performance in the given scenario. However, TDE is not a feasible solution because of its exhaustive computational complexity. Hence, we propose the use of FDE with the above mentioned parameters for Indoor UWB systems.
