Abstract

In this paper, we present results on the application of reduced-rank adaptive filtering techniques to the problem of interference suppression in ultra-wideband (UWB) communications. It is shown that reduced-rank optimum combining (OC) methods, in particular the eigen-canceler (EC), are effective in suppressing interference modeled as 802.11a signals. Simulation results are presented to show that the EC requires a shorter data record than minimum mean square error (MMSE) RAKE receivers.

本文介绍了在超宽带通信中应用降阶自适应滤波技术抑制干扰的研究结果。研究表明，降阶最优组合(OC)方法，特别是特征消除(EC)方法，可以有效地抑制802.11a信号的干扰。仿真结果表明，与最小均方误差(MMSE) RAKE接收机相比，EC接收机需要更短的数据记录。
