  abstract={In this paper we present an analysis of the generalized sidelobe canceller (GSC). It can be shown that the theoretical limits of the noise reduction performance depend only on the auto- and cross-spectral densities of the input signals. Furthermore, we compute the limits of the noise reduction performance for the theoretically determined diffuse noise field, which is an approximation for re-verberant rooms. Our results will show that the GSC cannot reduce noise further than 1dB. These results were verified by simulation of reverberant environments. Only in sound-proof rooms with a reverberation time less than 100ms the GSC performs well.},
