Acoustic Beamforming on Wireless Sensor Nodes

Acoustic beamforming is described in general terms, and the problems of implementing online acoustic beamforming on a wireless sensor node are described. A low-power FPGA-based solution is presented, implemented on a sensor board for a MicaZ mote. An integrated FFT-based frequency filter is also pre...
