摘要

提出了一种将传统宽带滤波器与基于线性预测的自适应滤波相结合的新型滤波器系统。这不仅允许减少，而且还允许频谱整形引起的噪声，例如在调频无线电链路。使用模拟应用程序的评估显示，与传统的compander系统相比，感知音频质量显着增加。

Compander systems with adaptive preemphasis/deemphasis using linear prediction

A new class of compander systems is proposed that combines conventional broad-band companders with adaptive filtering based on linear prediction. This allows not only for reduction, but also spectral shaping of noise induced e.g. in FM radio links. Evaluation using a simulation application shows a significant increase in perceived audio quality compared to conventional compander systems.
