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 s...

Zusammenfassung: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.
