摘要

本文研究了无参考自适应干扰消除技术。介绍了一种新的单输入交叉耦合自适应干扰消除器(CC-AIC)。该方案能够消除宽带信号中的窄带干扰(NBI)或窄带信号中的宽带噪声，其消除性能明显优于传统技术。即使当干扰相对于期望信号具有较小的功率谱密度时，也可以获得抵消，反之亦然。此外，该方案还可以有效地用作语音增强器。

Reference-free adaptive interference cancellation using cross-coupled scheme

This paper deals with the reference-free adaptive interference cancelling techniques. A new cross-coupled adaptive interference canceller (CC-AIC), with only a single input is introduced. This scheme is capable for cancelling narrow-band interference (NBI) from a broadband signal or wideband noise from a narrow-band signal with a significantly better cancellation performance than the conventional techniques. Cancellation was obtained even when the interference has a small power spectral density with respect to the desired signal and vice versa. Furthermore, this scheme can also be used efficiently as a speech enhancer.
