Performance evaluation of band-limited LPC vocoder and band-limited RELP vocoder in adaptive feedback cancellation

Abstract

Feedback oscillation is one of the major problems faced by the hearing aid users. Adaptive feedback cancellation is used to suppress the feedback by using an adaptive filter to estimate the feedback path. However, this estimate is biased due to presence of high correlation between the original input signal and the loudspeaker input signal. Bias problem… (More)
