中文摘要：

针对UWB（Ultra Wideband）系统在不同室内环境下信道不同对ISI抑制带来的影响，提出了一种可调观察窗口长度分数间隔线性均衡的（AOWL—FSLE）均衡接收机．该接收机能够根据室内信道不同，自适应地调整观察窗口长度．研究结果表明，当信道变化时，与固定观察窗口长度分数间隔线性均衡的（FOWL—FSLE）均衡接收机相比，该接收机能够更有效地抑制ISI影响，提高系统的BER性能．

英文摘要：

To suppress the effect that differences of channel in different indoor environment bring to mitigation of ISI for UWB receiver, an adjustable observation window length-fractionally spaced linear equalization （AOWL-FSLE） equalization receiver is proposed in this paper. The receiver can adaptively select the observa- tion window length according to difference of channel. Simulation results show that when channel changed, compared with fixed observation window length-fractionally spaced linear equalization （FOWL-FSLE） equali- zation receiver, the AOWL-FSLE equalization receiver can achieve better BER performance, because it can suppress the effect of ISI more effectively.
