The PEM-AFROW algorithm has been developed to model a room impulse response under closed-loop conditions, such as in microphone-amplifier-loudspeaker systems, and is particularly suited for a speech signal input. If a controller is inserted in the loop that uses this model to remove the loudspeaker signal component from the microphone signal, an efficient feedback cancellation can be performed. Crucial implementation-oriented issues that have not been studied so far are addressed. In particular, adaptation control mechanisms are proposed for feedback cancellation based on PEM-AFROW, and efficient subband and frequencydomain implementations are provided for this algorithm.
