| 摘要: |
| 由于高传输速率及多径效应的影响，在窄脉冲超宽带（IR-UWB）通信系统中，基于传统横向滤波器的时域均衡技术已无法对抗严重的码间干扰。通过收发两端联合设计，提出了一种以数据块为基础的基于码元的频域均衡技术，同时介绍了其应用前提和算法实现。仿真结果表明，所提方法能有效对抗超宽带通信系统中存在的码间干扰，是窄脉冲超宽带通信系统中更为现实的技术选择。 |

| Abstract: |
| Due to high transmission rate and multipath effect in narrow-pulse ultra-wideband (UWB) communication system,the time domain equalization technology based on traditional transversal filter is unable to deal with sever inter symbol interference(ISI). By joint design of receiver and transmitter,a frequency domain equalization algorithm based on data block transmission is proposed and its application precondition and implementation are introduced. The simulation result shows that the proposed algorithm can effectively resist inter symbol interference(ICI) in UWB communication system and it is a more realistic alternative for IR-UWB systems. |
