Abstract :
This work presents a noise cancellation structure with a fixed beamformer front end. Simulation results show a noise reduction of 21 dB with a speech source-noise source separation of 1m. Moreover, experimental results (real data acquired in a reverberant conference room) show a complex noise reduction pattern with a maximum noise reduction of 17 dB.
