Abstract: A device includes one or more processors configured to perform signal processing including a linear transformation and a non-linear transformation of an input signal to generate a reference target signal. The reference target signal has a linear component associated with the linear transformation and a non-linear component associated with the non-linear transformation. The one or more processors are also configured to perform linear filtering of the input signal by controlling adaptation of the linear filtering to generate an output signal that substantially matches the linear component of the reference target signal.

Abstract: Methods, systems, computer-readable media, and apparatuses for signal enhancement are presented. One example of such an apparatus includes a receiver configured to produce a remote speech signal from information carried by a wireless signal; a signal canceller configured to perform a signal cancellation operation on a local speech signal to generate a room response; and a filter configured to filter the remote speech signal according to the room response to produce a filtered speech signal. In this example, the signal cancellation operation is based on the remote speech signal as a reference signal.
