Abstract
A multi-beam sound system includes a fixed beamforming section which steers the input signal inputted from the microphone array to an intended direction, a blocking matrix which receives the input signal and acquires a noise reference signal from the input signal, a variable beamforming section which acquires an adaptive noise signal from the noise reference signal outputted from the blocking matrix, and a generalized sidelobe canceller (GSC) which includes canceling means for outputting an object signal from the input signal outputted from the fixed beamforming section by removing the adaptive noise signal from the input signal. The fixed beamforming section steers the input signal in at least two directions.
