Characterisation and modelling of non-linear loudspeakers
2014
2014 14th International Workshop on Acoustic Signal Enhancement (IWAENC)
Approaches to non-linear acoustic echo cancellation for mobile devices all require a reliable, non-linear model of the loudspeaker. This paper investigates a recent approach to nonlinear system identification. The loudspeaker is characterised using specially-crafted test signals, in this case simple exponential sine-sweep inputs, which facilitate the derivation of a polynomial Hammerstein model. Model performance is then assessed using the same artificial test input signal and then using
