We propose a combination of the well known generalized sidelobe canceller (GSC) or Griffiths-Jim beamformer, and the so-cal led PEM-AFROW algorithm for closed loop room impulse response estimation, resulting in a system for multimicrophone proactive acoustic feedback cancellation. For public address applications in low-reverberant environments, the computational complexity is re- duced dramatically compared to state of the art proactive acous- tic feedback cancellers, while performance is only marginally de- graded. |
