摘要

近年来，超宽带脉冲无线电(UWB-IR)由于具有体积小、功耗低、千兆数据传输等特点，在近距离通信领域受到了广泛关注。由于有限的发射功率发射，Rake接收应该是必要的，以达到所需的Eb/N0，但它对终端来说是不可接受的。因此，在接入点侧使用时间反转UWB-IR (TiR)方案被认为是实现Rake分集组合的一种有前途的解决方案。TiR有望应用于多小区信道，但小区间干扰(ICI)尚未得到研究。本文对TiR的ICI进行了实验研究，并与传统的UWB-IR进行了比较。基于光线追踪的计算机模拟与实验结果吻合较好。结果发现，使用TiR方案可以抑制ICI的影响。

ICI of time-reversal UWB-IR communication

Recently, ultra-wideband impulse radio (UWB-IR) has attracted considerable attention in short-range communications because it offers small-size, low power consumption and gigabit data transmission. Rake reception should be necessary to attain the required Eb/N0 because of the limited transmit power emission, but it will be unacceptable for the terminal. Therefore, the use of time-reversal UWB-IR (TiR) scheme at the access-point side has been suggested as a promising solution to achieve Rake diversity combining. The TiR is expected to be used in multi-cell channel, but the inter-cell interference (ICI) has not investigated. In this paper, the ICI of TiR is experimentally investigated and compared with a conventional UWB-IR. Ray-Tracing based computer simulation also is done to show good agreement with experiment. As a result, the effect of ICI is found to be suppressed by using the TiR scheme.
